MATLAB code for DCT based Gray-scale 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;
