Thanks to Syed Zeeshan Haider 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
Zeeshan has made changes after which user can now specifiy lots of options at the command prompt
fileName,quantizationTable,outputfilename,motionEstimation Algorithm ,before that all of this was hard coded

This is the error I'm getting when I run the code.

Error using blockproc>parse_inputs
(line 1034)
Invalid block function. BLOCKPROC
expects the user function, FUN, to
be a valid function handle.

Error in forwardDCT (line 4)
y = blkproc(Im,[8 8],'P1*x*P2',T,T');

Error in main44a (line 43)
JQ=forwardDCT(I1,array);

Thank you sir for posting this.
I am using MatlabR2010A.When i run this i am geeting the following error

Error using ==> fscanf
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in ==> main44 at 12
array=fscanf(fid,'%e',[8,inf]);

Thanks in advance

sir, we are currently working on video compression techniques and we are using ur codes and it is a good help for us but still we have not achieved compression ratio of even 10%..please help us regarding this. pliz provide ur mail id
