Image compression

Image Compression with Huffman Coding, DFT, DCT and WHT.

Here is python implementation for image Compression using Huffman Coding , Discrete Cosine Transform, Discrete Fourier Transform and Walsh-Hadamard Transform

This Compressions is explained in Digital Image Processing book by R.C. Gonzalez.
