This is important because Class 9th mathematics syllabus is given with the intent of making students relate various real-life problems with the mathematical concepts they study at this level.

Class 9th Mathematics syllabus is updated regularly according to the latest NCERT syllabus. Praadis Teachers also continuously produce new and improved content on all the chapters as per the new syllabus. This ensures that students' studies do not get affected by the inclusion or omission of any new chapter. All students are advised to prepare a list of chapters before the final academic exams for revision purposes. The chapters in the list should be arranged in decreasing order of priority. This will serve as a reminder for students to study the most difficult chapters early while revising a subject.

Amazon’s Incredible Web Of Businesses Shows Just How Large Its Ambitions Are

Everything about Amazon in 2019 is inconceivably big: Amazon will make up an estimated 38% of the US e-commerce market this year, according to the online commerce research firm eMarketer, and already dominates 67% of the online books, music, and video market; 46% of the online computer and electronics market; 45% of the online toy market; and 34% of online furniture sales. And with more than $25 billion in revenue just from Amazon Web Services last year, Amazon is the world’s largest cloud services provider.

Its sheer size and influence has caught the attention of regulators and lawmakers like Sen. Elizabeth Warren, who proposed a plan to break up Amazon and other technology companies in March. In its defense, Amazon said it makes up just 4% of all US retail sales.

But taken as a whole, Amazon is much more than a retail platform. The company — which originally incorporated on July 5, 1994, under the business name “Cadabra” and started selling books under the new name Amazon on July 16, 1995 — has expanded into a complex web of businesses and subsidiaries that make it easy to walk into and difficult to walk out of. Its reach stretches from review sites like Goodreads to shoe sales on Zappos to devices like Ring to baby clothing sold in its marketplace to educational tools for teachers, like entire math curriculums.

Few corners of business are untouched by Amazon. You might be shopping on an Amazon-owned site even if you don’t think you are, or be looking at a website or using an app that uses one of many of Amazon’s web services.

We compiled this list of all Amazon’s businesses and subsidiaries in honor of the company’s anniversary. In addition to the countless companies Amazon has acquired and services it has launched, we found Amazon has more than 80 private-label brands across all categories, including a dozen women’s clothing brands and (inexplicably) seven denim brands, showing how the company has expanded quietly, but at an aggressive pace. Quartz reported that Amazon has either been awarded or applied for 800 trademarks.

This list is not exhaustive (the company is pretty hush-hush about its businesses), some of the listed businesses here have been discontinued or absorbed into other services on the list, and there were lots of questions about how to categorize certain things. So the list is imperfect, but the point is: there are hundreds of products, brands, and services that Amazon offers that often don’t even use the Amazon name. Take a look at what’s already crossed our radar — this is just the surface, and surely there are many more to come.

Let’s get started.

Overview

This post is divided into three parts; they are:

Top 5 Computer Vision Textbooks

Top 3 Computer Vision Programmer Books

Recommendations

Top 5 Computer Vision Textbooks

Textbooks are those books written by experts, often academics, and are designed to be used as a reference for students and practitioners.

They focus mainly on general methods and theory (math), not on the practical concerns of problems and the application of methods (code).

I gathered a list of the top five textbooks based on their usage in university courses at top schools (e.g. MIT, etc.) and recommendations on discussion websites (e.g. Quora, etc.).

The top five textbooks on computer vision are as follows (in no particular order):

Computer Vision: Algorithms and Applications, 2010.

Computer Vision: Models, Learning, and Inference, 2012.

Computer Vision: A Modern Approach, 2002.

Introductory Techniques for 3-D Computer Vision, 1998.

Multiple View Geometry in Computer Vision, 2004.

Let’s take a closer look at each in turn, including the target audience and table of contents for each book.

Computer Vision: Algorithms and Applications

This book was written by Richard Szeliski and published in 2010.

Computer Vision: Algorithms and Applications

A draft version of the book in PDF format is available from the book’s homepage.

I like this book. It provides a strong foundation for beginners (undergraduates) in computer vision techniques for a wide range of standard computer vision problems. The book was developed by Richard based on his years of experience teaching the topic at the University of Washington.

This book also reflects my 20 years’ experience doing computer vision research in corporate research labs […] I have mostly focused on problems and solution techniques (algorithms) that have practical real-world applications and that work well in practice. Thus, this book has more emphasis on basic techniques that work under real-world conditions and less on more esoteric mathematics that has intrinsic elegance but less practical applicability.

Computer Vision: Models, Learning, and Inference

This book was written by Simon Prince and published in 2012.

Computer Vision: Models, Learning, and Inference

A draft version of the book is available on the book’s website in PDF format.

This is a great introductory book (for students) and covers a wide range of computer vision techniques and problems. The book takes more time to introduce computer vision and spends useful time on foundational topics related to probabilistic modeling.

This modern treatment of computer vision focuses on learning and inference in probabilistic models as a unifying theme. It shows how to use training data to learn the relationships between the observed image data and the aspects of the world that we wish to estimate, such as the 3D structure or the object class, and how to exploit these relationships to make inferences about the world from new image data.

Computer Vision: A Modern Approach

This book was written by David Forsyth and Jean Ponce and published in 2011.

Computer Vision: A Modern Approach

This is an introductory textbook on computer vision and is perhaps more broad in the topics covered than many of the other textbooks. Although broad, it may be less loved (popular) than some of the other introductory text as it can be challenging to read: it dives right in.

… vision relies on a solid understanding of cameras and of the physical process of image formation (Part I of this book) to obtain simple inferences from individual pixel values (Part II), combine the information available in multiple images into a coherent whole (Part III), impose some order on groups of pixels to separate them from each other or infer shape information (Part IV), and recognize objects using geometric information or probabilistic techniques (Part V).

Multiple View Geometry in Computer Vision

This book was written by Richard Hartley and Andrew Zisserman and was published in 2004.

Multiple View Geometry in Computer Vision

Samples of some of the chapters are available in PDF format from the book’s webpage.

It is a reasonably advanced book (graduate level) on a specialized topic in computer vision, specifically on the problem and methods related to inferring geometry from multiple images.

The book is divided into six parts and there are seven short appendices. Each part introduces a new geometric relation: the homography for background, the camera matrix for single view, the fundamental matrix for two views, the trifocal tensor for three views, and the quadrifocal tensor for four views.

Top 3 Computer Vision Programmer Books

Programmer books are playbooks (e.g. O’Reilly books) written by experts, often developers and engineers, and are designed to be used as a reference by practitioners.

They focus mainly on techniques and the practical concerns of problem solving with a focus on example code and standard libraries. Techniques may be described briefly with relevant theory (math) but should probably not be used as a primary reference.

I’ve gathered a list of the top three playbooks based on their rank ordering in lists of top computer vision books and on recommendations on discussion websites.

The top three textbooks on computer vision are as follows (in no particular order):

Learning OpenCV 3, 2017.

Programming Computer Vision with Python, 2012.

Practical Computer Vision with SimpleCV, 2012.

Let’s take a closer look at each in turn, including the target audience and table of contents for each book.

Learning OpenCV 3

This book was written by Adrian Kaehler and Gary Bradski and published in 2017. The subtitle of the book is “Computer Vision in C++ with the OpenCV Library.”

Learning OpenCV 3

The book focuses on teaching you how to use the OpenCV library, perhaps the premiere open source computer vision library. All code examples are in C++, suggesting that the target audience are professional developers looking to learn how to incorporate computer vision into their applications. Importantly, the authors are board members and founders of OpenCV.

It is a technical book and perhaps more an elaborated API documentation than a playbook.

This book provides a working guide to the C++ Open Source Computer Vision Library (OpenCV) version 3.x and gives a general background on the field of computer vision sufficient to help readers use OpenCV effectively.

— Learning OpenCV 3, 2017.

This book may be considered an updated version of the older (2008) book Learning “OpenCV: Computer Vision with the OpenCV Library” by the same authors.

Programming Computer Vision with Python

This book was written by Jan Erik Solem and published in 2012. The subtitle for the book is “Tools and algorithms for analyzing images.”

Programming Computer Vision with Python

A final draft version of the book is available from the book’s website in PDF format.

This is a hands-on book that focuses on teaching you how to perform basic computer vision tasks in Python, mostly with PIL, although with a basic introduction to OpenCV as well. I’m a fan of this book, although minor modifications are required to use updated libraries (e.g. Pillow). An update to this book is due!

The idea behind this book is to give an easily accessible entry point to hands-on computer vision with enough understanding of the underlying theory and algorithms to be a foundation for students, researchers, and enthusiasts.

7. Searching Images

8. Classifying Image Content

9. Image Segmentation

10. OpenCV

Practical Computer Vision With SimpleCV

This book was written by Kurt DeMaagd, Anthony Oliver, Nathan Oostendorp, and Katherine Scott, and was published in 2012. The subtitle of the book is “The Simple Way to Make Technology See.”

Practical Computer Vision with SimpleCV

This book teaches you how to perform basic computer vision operations using the SimpleCV library in Python. This provides a nice alternative to working with PIL (Pillow) or OpenCV, although I’m not convinced that SimpleCV has been broadly adopted (I’m happy to be proven wrong).

Learn how to build your own computer vision (CV) applications quickly and easily with SimpleCV, an open source framework written in Python. Through examples of real-world applications, this hands-on guide introduces you to basic CV techniques for collecting, processing, and analyzing streaming digital images.

10. Advanced Features

Recommendations

I love books and am reading a few different books at any one time. As such, I own all of the books listed in this post.

Nevertheless, if I was forced to recommend one textbook and one playbook, my recommendations would be as follows:

Recommended Textbook

Computer Vision: Algorithms and Applications, Richard Szeliski, 2010.

I recommend this book because it provides a short, focused, and very readable introduction to computer vision with relevant theory, without getting too bogged down. Straight to the point and a useful reference text.

Recommended Programmer Book

Programming Computer Vision with Python, Jan Erik Solem, 2012.

I recommend this book because it focuses on real computer vision techniques with standard (or close enough) Python libraries. It’s an excellent starting point for getting your hands dirty in computer vision.

Amazon’s Incredible Web Of Businesses Shows Just How Large Its Ambitions Are

Everything about Amazon in 2019 is inconceivably big: Amazon will make up an estimated 38% of the US e-commerce market this year, according to the online commerce research firm eMarketer, and already dominates 67% of the online books, music, and video market; 46% of the online computer and electronics market; 45% of the online toy market; and 34% of online furniture sales. And with more than $25 billion in revenue just from Amazon Web Services last year, Amazon is the world’s largest cloud services provider.

Its sheer size and influence has caught the attention of regulators and lawmakers like Sen. Elizabeth Warren, who proposed a plan to break up Amazon and other technology companies in March. In its defense, Amazon said it makes up just 4% of all US retail sales.

But taken as a whole, Amazon is much more than a retail platform. The company — which originally incorporated on July 5, 1994, under the business name “Cadabra” and started selling books under the new name Amazon on July 16, 1995 — has expanded into a complex web of businesses and subsidiaries that make it easy to walk into and difficult to walk out of. Its reach stretches from review sites like Goodreads to shoe sales on Zappos to devices like Ring to baby clothing sold in its marketplace to educational tools for teachers, like entire math curriculums.

Few corners of business are untouched by Amazon. You might be shopping on an Amazon-owned site even if you don’t think you are, or be looking at a website or using an app that uses one of many of Amazon’s web services.

We compiled this list of all Amazon’s businesses and subsidiaries in honor of the company’s anniversary. In addition to the countless companies Amazon has acquired and services it has launched, we found Amazon has more than 80 private-label brands across all categories, including a dozen women’s clothing brands and (inexplicably) seven denim brands, showing how the company has expanded quietly, but at an aggressive pace. Quartz reported that Amazon has either been awarded or applied for 800 trademarks.

This list is not exhaustive (the company is pretty hush-hush about its businesses), some of the listed businesses here have been discontinued or absorbed into other services on the list, and there were lots of questions about how to categorize certain things. So the list is imperfect, but the point is: there are hundreds of products, brands, and services that Amazon offers that often don’t even use the Amazon name. Take a look at what’s already crossed our radar — this is just the surface, and surely there are many more to come.
