Image Processing and Convolutional Filters

This lesson dives into some image processing concepts and reviews convolution operations that become important later in this course. It is therefore important to review this lesson well. Also, the discussion gives us the opportunity to practice Python programming a bit more.

We have already displayed gray-scale images that were given by 2-dimensional matrices where each component stands for a gray level of one pixel. In order to represent color images, we just need three channels that each stands for one primary color, red (R), green (G), and blue (B).
