Scalable MPEG compression based on DCT coefficients

This application makes 2 layers base Layer and enhancement layer from quantized coefficients

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality..
This application only works for gray scale.
Although this program will do its work but its slow.
This code is without any comments i will try to add them. but for the time being if u have hard time understanding it you can always contact me
