Project "ML.Satellite": Image Parser

In order to speed up the "manufacturing" of the training dataset as much as possible, extreme automation is necessary. Hence, the next step was to create a semi-automatic satellite multispectral Image Parser.

Firstly, it should carve the smaller pieces from the big picture and adjust them linearly, providing radiometrical rescaling, since spectrometer produces somewhat distorted results compared to the actual radiance of the Earth's surface. These "pieces" will comprise the dataset. It was proposed to "manufacture" about 400 such "pieces" in a 500 by 500 "pixels" format.

P.S.: Below are example images of the procedure described above. (Novaya Zemlya Archipelago)

Secondly, it should calculate some remote sensing indexes. For this task, a list of empirical indexes was taken: NDVI, NDWI, MNDWI, NDSI, ANDWI (alternatively calculated NDWI), WRI and NDTI. Only several of them were useful for the project purposes.

P.S.2: The following are example images of the indexing procedure.

Lastly, it should compute the "labels" for the "pieces" describing a schematic map of the territory on image splitting this territory into several types according to the calculated indexes. To simplify segmentation, in our project, a territory can consist only of the following types: Clouds, Water (seas, oceans, rivers, lakes…), Vegetation (forests, jungles…), Snow and Land (this class includes everything else). And, of course, Parser should save the processed dataset and labels.

P.S.3: Below are sample image of a colored "piece" and a simple map based on the label assigned to this "piece". Map may seem a drop inaccurate and it's not surprising, since as far as I know, indexes are empirical and by definition cannot be precise. As a result, if it is possible to create a sufficiently accurate model that predicts analytical classification, then it may be possible to create a model that classifies optical images better than analytics.

Project "ML.Satellite": Launch

The new semester brings to me a new ML project. A prerequisite for getting a good grade for a mandatory data analysis course is to create the beneficial neural network of medium complexity. Thus, I started a project "Machine learning model for the terrain segmentation".

The idea of project is to train a model which could divide the multispectral satellite images into parts by type of terrain (to mark where land and water are in the image, where forest and snow are, etc.) An analytical solution for this task does exist, but it appears to be empirical in nature. And it would be really nice to devise a model independent of this solution. But I haven't been able to find a useful dataset for such a task, therefore this task is getting more and more difficult since I need to create such a dataset. First of all, this dataset will be created using an analytical solution, so the goal changes from trying to beat the analytical solution to trying to catch up with the existing solution. The resulting dataset will be published by the end of the project.

The dataset will be "manufactured" using the data from the Landsat 8 satellite. It provides the images of 11 bands with an aspect size of about 5000-10000 "pixels", excluding the 8th band of doubled size.

P.S.: Below is an example of an image band reduced in size by 10 times.

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. The technology could enable household testing for arsenic, empowering individuals to monitor their own water quality. Arsenic contamination is a serious environmental and public health challenge affecting millions of people around the world. This contamination occurs when natural geological processes release arsenic from rocks and soil into groundwater and can be exacerbated by mining, industrial waste disposal and use of arsenic-based pesticides. "Consuming arsenic-contaminated water can lead to severe health conditions including arsenic poisoning and cancers of the skin, lung, kidney and bladder," said lead researcher Sunil Khijwania from the Indian Institute of Technology Guwahati. "By creating a sensor that is sensitive, selective, reusable and cost-effective, we aim to address the need for a reliable and user-friendly tool for routine monitoring, helping to protect communities from the risks of arsenic exposure."

nova moment i won’t get to for ages but wanna talk about bc it’s really fucking funny- when amy has her bat mizvah she obviously like. invites her friends. and nova is her best friend and bc of this she’s obviously also invited. and she just spends the entire time in awe bc she's got a special interest in religious text while also having never had any knowledge of actual religious practices. after during celebrations she's just BEGGING amy to know how she can come back to the synagogue bc she had the best night of her life that didn't involve murder she's utterly awestruck. like she legitimately Did Not Know religion was like this and she’s stoked. like down to convert on the spot stoked. (amy encourages her to do more research first bc obviously nova doesn’t have the informed ability to make that choice when she barely knows anything about religion except the scripture isolated from any context but she does take nova to synagogue when she’s in station square)
