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
Mr. Zahid Ali Has done a wonderful work. It helped me alot with my research "managing drift in scalable video coding". A good job done.

Bytheway the enhancement layer is not the DC component of 8X8 transformed coefficient matrix. It is found by subtracting the recontructed image from the original frame at the encoder...In efficient and incomplete.
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
The changes are only made in the threshold coding.I have made a function of a main file (from where excecution starts,the name of file is main.m) so that user can pass file name and quantization table name through parameters.I have also added warning if no filename for video and quantization table is not provided.
can any body tell how to run this code submitted by Zahid Ali, when i try to enter the file name( i think input video),quantization table(by giving its path),out putfile name(i think where the out put will be kept after compression)& estimation algorithm it is not working. give me sample examples
too urgent !

hello Zahid Ali, i have question. At present i'm doing my final project. i research about the video processing, so in many of codes that you give, i don't know where i have to start.
Please explain for me. Thank you a lot
when i run BmotionEstARPS.m, Matlab warning this :
"Warning: Size vector should be a row vector with integer
elements"
so please show me how to fix it. thanks
can any body tell me please how to run this code. I don't know where i have to start.
And if there are some commenting code file, it's interesting for me because I started working on compression / decompression of video.
tanx a lot!
