MATLAB code for DCT based Color Image Compression.

Number of bits required to represent the information in an image can be minimized by removing the redundancy present in it
There are three types of redundancies:
1. Spatial redundancy
Which is due to the correlation or dependence between neighboring pixel values;
2. Spectral redundancy,
Which is due to the correlation between different color planes or spectral bands;
