The class generated dynamically is more complex than the one described in the previous article, this time we have to store all the array objects, the parameter values, and the indices i, j. Now I have the boundaries. Complementing Michel Laufer's answer: usually the range of colors a pixel can take goes from (0-255) for each channel (red, green, blue), which is a different way of saying that each channel is encoded by a 8-bit positive integer. MATLAB offers many flexible tools for analyzing numbers, and MATLAB strings help you understand what the numbers mean. The following Matlab project contains the source code and Matlab examples used for image registration (2d) using mutual information (optimization toolbox needed).
