Computer Vision is all about math. When you need to create your own algorithm or implement something, you address a math topic. You should know how it works on the inside because without digging into the basics, it is hard to do anything. But you are not alone! Many smart people have created several useful libraries to simplify your job. One of those libraries is JSFeat (http://inspirit.github.io/jsfeat/), which has a realization of different math methods. Here, we will discuss fundamental elements of the library such as data structures, especially matrices, and simple math algorithms.
We will cover the following topics:
Installation and core structure representation of JSFeat
What is inside an image? All about matrices
Useful functions and where to use them
