The following Matlab project contains the source code and Matlab examples used for scalable mpeg compression based on dct 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.
The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
