The function CalcImgEntropy() calculates the entropy of the colors of a `UINT8` image with single or multiple (Up to 8) channels.
It supports 2 modes:
  1. Calculation per Channel: It averages the entropy calculated on each channel seperatly.
  2. Calculation per Image (Vector): Concatentae each pixel to have a single value representation.
The current implementation uses the arguments block both for the input and the output. Hence it requires MATLAB R2022b. In case you have an earlier version one might remove those blocks and the code should be compatible with earlier versions.
The function was created as an answer to the question StackExchnage - Signal Processing - What Measure to Compare the Color Depth (Distribution of Colors) of Images.
See my StackExchnage Codes Project.
