With the standardization of MPEG-4 object-based compression has become an important technique. This project was focused towards develpoping wavelet based compression schemes which follow the object-based coding paradim in the sense of MPEG-4 as well. In particular, main emphasis was given to adaptive and hybrid coding techniques in order to compensate for the loss in compression performance caused by increased functionality. Wavelet packets, matching pursuits, wavelet filter parametrizations, and hybrid video coding schemes have been the main technical ingredients to this project.
