it is in times like these that it is helpful to remember that all of medical science that isn't like, infectious disease, but PARTICULARLY psychiatry is a bunch of fake ass idiots who dont know how to do science, and when you hear about it on tiktok, it's being reinterpreted through somebody even dumber who is lying to you for clicks. as such you should treat anything they say as lies.

u do this wiggle because it's a normal thing to do.

anyways i looked at this paper. they stick people (n=32) on a wii balance board for 30 seconds and check how much the center of gravity moves. for AHDH patients, it's 44.4 ± 9.0 cm (1 sigma) and for non ADHD patients its 39.5 ± 7.2 cm (1 sigma)

so like. at best the effect size is 'wow. adhd people shift their weight, on average, a tiny bit more than non-adhd people, when told to stand still'.

in summary, don't trust tiktok, and:

every once in a while i learn some wild new piece of information that explains years of behavior and reminds me that i will never truly understand everything about my ridiculous adhd brain

DXO Pure Raw 4

Comparing DXO Pure Raw 4 to Topaz Photo AI version 2.4 in my real world comparison using it as a pre-processor to Adobe Camera Raw and Photoshop. The Problem Unfortunately it has come to my attention that all of my software licenses are expiring this month. That includes DXO Pure Raw 3, and all the Topaz products including Gigapixel, and Photo AI. The two stand alone products Sharpen AI and…

finally went and started looking into nightshade because it sounds. dubious. apparently the project's full title is "nightshade: protecting copyright". it is absolutely wild that a bunch of internet communists saw that and went "yeah this is a good thing, we should totally rally around this"

[kimsuyeon]

updated stage settings: (that literally no one asked for!)

assumes knowledge of photoshop and a working vapoursynth. if you don't use vs, you can replicate with mpv - though sharpening will most likely need to be stronger, since i use finesharp in vs.

when using mpv/screencaps, i recommend importing as a dicom file! it loads faster and is a little clearer in my opinion. when using screencaps, only crop once. if you need to change the dimensions, zoom, etc., i would undo to the full size you imported at or it will lower your quality.

examples: an ending fairy of cravity's seongmin, and a typical stage set gif (using a close-up) of tripleS's kaede. shows the steps, effects, and goals of sharpening and coloring, but does not share psds or actions since i recommend using your own unique sharpening and coloring style. psds cannot be provided (i didn't save them) but i will share my actions if asked to! the actions i used are the two i almost always use (with a few exceptions) on stage gifs.

no keep reading because it ruins formatting (2 images side by side), so apologies for the incredibly long post!

ending fairy:

run through vapoursynth, resized (540 x 420) and sharpened with finesharp set to 0.7 (the last # in the fs code). not preprocessed, as i wanted the normal speed and exported it with a .04 frame delay!

sharpened using my stage sharpening action (4 diff smart sharpens)

colored using levels (using the eyedropper on what i want to be pure black), and curves (done to add contrast, using only the rgb channel)

colored (prev step still visible) using exposure, with the exposure upped and gamma around .90. also used brightness and contrast to get the look i wanted, while also keeping highlights in a range that i can edit (going too bright or too high contrast makes my later adjustments less effective)

colored (prev steps visible) using hue/saturation (adjusting the hue, saturation, and lightness (to the negatives) of reds and yellows), and selective color (fine-tuning tone of reds and adjusting whites)

colored (prev steps visible) using selective color (adding back some white and adding cyan to it), and hue/saturation to further fine-tune (red + yellow), and brightness and contrast to get the final brightness and contrast/clarity i wanted.

the original (resized and with vs finesharp) masked over the finished

close-up:

run through vs, resized (268 x 490), preprocessed 60fps slow, and sharpened with a finesharp of 0.7

sharpened using my master mv sharpening (i changed the gaussian blur 500 from .04 to .03, + the unsharp mask is set to 50% opacity)

colored using levels (on what i want to be pure black, her hair by her ear in this case), and curves (unlike seongmin's which just adjusted rgb, i also changed the blue and green channels! i do this when it is not an ending fairy but several close-ups to try to make the coloring more consistent across lighting changes (i also do it on more challenging lighting from other sources))

colored with exposure (prev steps visible), with exposure upped (+) and gamma adjusted (~.90), and brightness and contrast to get the look i want (same highlight forethought as before)

colored (prev steps visible) with hue/saturation (adjusting hue, saturation, and lightness of reds and yellows), selective color (fine-tuning tone of reds and adjusting whites)

colored with selective color (adding back whites and adding cyan to them), hue/saturation to further fine-tune, and brightness and contrast to get the final look and clarity

optional, but nice for multi-shot sets: another hue/sat above your last brightness contrast, only adjusting background colors for cohesion when paired with the other gifs of the set

also optional: change speed to be faster, depending on the look you want. i tend to use ezgif.com/speed and do 105% speed

the original (resized, vs finesharp, preprocessed to 60fps slow) masked over the finished gif. the one on the right has been adjusted with ezgif at 105% speed

Unlock the other 99% of your data - now ready for AI

New Post has been published on https://thedigitalinsider.com/unlock-the-other-99-of-your-data-now-ready-for-ai/

Unlock the other 99% of your data - now ready for AI

For decades, companies of all sizes have recognized that the data available to them holds significant value, for improving user and customer experiences and for developing strategic plans based on empirical evidence.

As AI becomes increasingly accessible and practical for real-world business applications, the potential value of available data has grown exponentially. Successfully adopting AI requires significant effort in data collection, curation, and preprocessing. Moreover, important aspects such as data governance, privacy, anonymization, regulatory compliance, and security must be addressed carefully from the outset.

In a conversation with Henrique Lemes, Americas Data Platform Leader at IBM, we explored the challenges enterprises face in implementing practical AI in a range of use cases. We began by examining the nature of data itself, its various types, and its role in enabling effective AI-powered applications.

Henrique highlighted that referring to all enterprise information simply as ‘data’ understates its complexity. The modern enterprise navigates a fragmented landscape of diverse data types and inconsistent quality, particularly between structured and unstructured sources.

In simple terms, structured data refers to information that is organized in a standardized and easily searchable format, one that enables efficient processing and analysis by software systems.

Unstructured data is information that does not follow a predefined format nor organizational model, making it more complex to process and analyze. Unlike structured data, it includes diverse formats like emails, social media posts, videos, images, documents, and audio files. While it lacks the clear organization of structured data, unstructured data holds valuable insights that, when effectively managed through advanced analytics and AI, can drive innovation and inform strategic business decisions.

Henrique stated, “Currently, less than 1% of enterprise data is utilized by generative AI, and over 90% of that data is unstructured, which directly affects trust and quality”.

The element of trust in terms of data is an important one. Decision-makers in an organization need firm belief (trust) that the information at their fingertips is complete, reliable, and properly obtained. But there is evidence that states less than half of data available to businesses is used for AI, with unstructured data often going ignored or sidelined due to the complexity of processing it and examining it for compliance – especially at scale.

To open the way to better decisions that are based on a fuller set of empirical data, the trickle of easily consumed information needs to be turned into a firehose. Automated ingestion is the answer in this respect, Henrique said, but the governance rules and data policies still must be applied – to unstructured and structured data alike.

Henrique set out the three processes that let enterprises leverage the inherent value of their data. “Firstly, ingestion at scale. It’s important to automate this process. Second, curation and data governance. And the third [is when] you make this available for generative AI. We achieve over 40% of ROI over any conventional RAG use-case.”

IBM provides a unified strategy, rooted in a deep understanding of the enterprise’s AI journey, combined with advanced software solutions and domain expertise. This enables organizations to efficiently and securely transform both structured and unstructured data into AI-ready assets, all within the boundaries of existing governance and compliance frameworks.

“We bring together the people, processes, and tools. It’s not inherently simple, but we simplify it by aligning all the essential resources,” he said.

As businesses scale and transform, the diversity and volume of their data increase. To keep up, AI data ingestion process must be both scalable and flexible.

“[Companies] encounter difficulties when scaling because their AI solutions were initially built for specific tasks. When they attempt to broaden their scope, they often aren’t ready, the data pipelines grow more complex, and managing unstructured data becomes essential. This drives an increased demand for effective data governance,” he said.

IBM’s approach is to thoroughly understand each client’s AI journey, creating a clear roadmap to achieve ROI through effective AI implementation. “We prioritize data accuracy, whether structured or unstructured, along with data ingestion, lineage, governance, compliance with industry-specific regulations, and the necessary observability. These capabilities enable our clients to scale across multiple use cases and fully capitalize on the value of their data,” Henrique said.

Like anything worthwhile in technology implementation, it takes time to put the right processes in place, gravitate to the right tools, and have the necessary vision of how any data solution might need to evolve.

IBM offers enterprises a range of options and tooling to enable AI workloads in even the most regulated industries, at any scale. With international banks, finance houses, and global multinationals among its client roster, there are few substitutes for Big Blue in this context.

Mastering MATLAB: Solving Challenging University Assignments

Welcome to another installment of our MATLAB assignment series! Today, we're diving into a challenging topic often encountered in university-level coursework: image processing. MATLAB's versatility makes it an invaluable tool for analyzing and manipulating images, offering a wide array of functions and capabilities to explore. In this blog, we'll tackle a complex problem commonly found in assignments, providing both a comprehensive explanation of the underlying concepts and a step-by-step guide to solving a sample question. So, let's roll up our sleeves and get ready to do your MATLAB assignment!

Understanding the Concept: Image processing in MATLAB involves manipulating digital images to extract useful information or enhance visual quality. One common task is image segmentation, which involves partitioning an image into meaningful regions or objects. This process plays a crucial role in various applications, including medical imaging, object recognition, and computer vision.

Sample Question: Consider an assignment task where you're given a grayscale image containing cells under a microscope. Your objective is to segment the image to distinguish individual cells from the background. This task can be challenging due to variations in cell appearance, noise, and lighting conditions.

Step-by-Step Guide:

1. Import the Image: Begin by importing the grayscale image into MATLAB using the 'imread' function.

image = imread('cells.jpg');

2. Preprocess the Image: To enhance the quality of the image and reduce noise, apply preprocessing techniques such as filtering or morphological operations.

filtered_image = medfilt2(image, [3 3]); % Apply median filtering

3. Thresholding: Thresholding is a fundamental technique for image segmentation. It involves binarizing the image based on a certain threshold value.

threshold_value = graythresh(filtered_image); % Compute threshold value binary_image = imbinarize(filtered_image, threshold_value); % Binarize image

4. Morphological Operations: Use morphological operations like erosion and dilation to refine the segmented regions and eliminate noise.

se = strel('disk', 3); % Define a structuring element morph_image = imclose(binary_image, se); % Perform closing operation

5. Identify Objects: Utilize functions like 'bwlabel' to label connected components in the binary image.

[label_image, num_objects] = bwlabel(morph_image); % Label connected components

6. Analyze Results: Finally, analyze the labeled image to extract relevant information about the segmented objects, such as their properties or spatial distribution.

props = regionprops(label_image, 'Area', 'Centroid'); % Extract object properties

DIP is constantly evolving, thanks to advancements in Artificial Intelligence (AI). Imagine self-driving cars using DIP for super-accurate navigation in real-time, or virtual reality experiences that seamlessly blend real and digital worlds with exceptional clarity. The possibilities are endless!

So, the next time you look at an image, remember, there's a whole world of technology working behind the scenes to make it what it is. With DIP, we can truly see beyond the pixel and unlock the hidden potential of the visual world around us.

A little output

I spent my lunch programming rather than eating, which is very typical of me when I get deeply involved in a project. I must make sure I don't fall into that obsession trap again, which has caused many burnouts in the past! 😅

My current task was to get the new generation machine to spit items out onto a connected belt. This was mostly straightforward, though it was a little tricky getting my head around supporting rotation.

Ultimately it came down to making things simple. Machines can either have an input or an output, or both. Since the side with which the machine accepts either inputs and outputs is defined at the prefab level (i.e. it's fixed based on what I set the model to), I just had to write some code to shift those input/output 'sides' depending on which of the 4 possible directions the model was placed in.

As far as handling exactly where the machine should look for an input / output belt, I kinda cheated a bit on this one.

The reason this was a little more complex is because machines can have a footprint of more than just 1x1, they can be 2x2 as well. A 2x2 machine will have a inputs / outputs on specific grid positions around its outside perimeter. How do I allow for this whilst enabling rotation of the placed object?

This. This is my cheat.

The little blob in the above image is an object that represents which grid position I want the machine to look for a belt (specifically an output belt). Because this blob is a child object of the machine, when the machine rotates - so the blob does too. At runtime, when I configure the machine, I can simply read the real-world position of the blob to get its grid coordinates. Neat!

It's easier to see top-down here:

The machine lives at grid position [6,4] and the blob lives inside the machine object at position [1,0]. Translated to absolute world position the blob lives at [7,4] - exactly where I need to be checking for belts!

I'm sure there are much better ways of doing this, but this was a pretty straightforward solution that only requires a tiny amount of preprocessing when the object is first placed, after which no additional calculation is needed.

With the positioning and belt-lookup code added, it was just a case of writing up a short Machine class, from which I derived a special 'InputMachine' class that only spits out items of a specific type.

The result you can see below!

Where is this all leading?

I suppose it's a good a time as any to review my future plans for these developments. What good are little prototypes without some larger goal in mind?

In one of my earliest posts I details the kind of game I'm hoping to make. Mechanically it's not super complicated, but it required figuring out some of the technical stuff I've been showing in recent posts - namely conveyor belts and moving items around.

I'm hoping to create a game that fits in the automation / factory genre. You'll be playing the role of someone setting up an automated factory that has been deposited and unpacked on a remote asteroid. You place down drills (inputs) that dig and spit out raw materials into your factory, and you move these around and process them in various machines in the name of science!

As I said this isn't the most complex of concepts. From a programming complexity point of view some of the legwork has already done (problem solving belts, specifically). There are areas that still need consideration, but looking over what's left to come I'm quietly confident it falls within my skill set to execute.

A cut down the middle

I expect anybody familiar with game development is aware of the term 'vertical slice'. It refers to the practice of developing a small segment of a product, but to a very polished state that could be considered represetative of its final form.

You see this a lot in game development. Particularly at conferences and exhibitions where publishers want to whip up excitement about games that could be years away from release. But there should be some delineation between a vertical slice for a trailer, and a playable vertical slice. I'm aiming for the latter.

In order to decide how to put something like that together, I need a broader understanding of the scope of the game. A vertical slice should demonstrate all the key concepts in the game, but leaving room to expand those ideas later without changing the core experience too much. It doesn't have to look like the final game either, though I would like to put some effort in there where possible.

I'll probably end this post here for now, but I'll probably detail out the main efforts I'm likely to be aiming for in order to reach this vertical slice. I will, of course, continue posting updates when I can with more details about the game's development.

And if you read this far and found some small measure of interest in here, thanks for your time and have yourself a great day! 😊

Workflow for generating 25 images of a character concept using Automatic1111 and Control Net image diffusion method with txt2img;

Enable Control Net , Low VRAM, and Preview checkboxes on.

Select the Open Pose setting and choose the openpose_hand preprocessor. Feed it a good clean source image such as this render of figure I made in Design Doll. Click the explodey button to preprocess the image, and you'll get a spooky rave skeleton like this.

Low VRAM user (me, I am low VRAM) tip: Save that preprocessed image and then replace the source image with it. Change the preprocessor to none, and it saves a bit of time.

Lower the steps from 20 if you like. Choose the DPM++SDE Karras sampler if you like.

Choose X/Y/Z plot from the script drop down and pick the settings you like for the character chart about to be generated. in the top one posted I used X Nothing Y CFG scale 3-7 Z Clipskip 1,2,3,7,12
