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

Thank you Zeeshan for correcting errors and adding error handling to the code and commenting my code.
Now main file which is main.m has a function and you can run it through command line by passing it arguments
