Entropy and Local Entropy of original and encrypted images

Compute entropy and local entropy of a plaintext image, its suffled version, and encrypted version.

This code can be used for computing the entropy and local entropy of a plaintext image, its shuffled version, and its encrypted version, for both grayscale and RGB images.

The image was encrypted using chaos based encryption techniques
