Advanced image compression techniques: comparative functionalities and performances

With the increasing use of multimedia techniques, image compression requires higher performance as well as new features. Image coding standards, including some newly developed ones (MPEG-4 VTC, JPEG2000), are reviewed. A comparative analysis of their performances and functionalities is also given. The results show that the choice of the best standard depends strongly on the application at hand, but that JPEG2000 supports the widest set of features among the evaluated standards, while providing superior rate-distortion performance in most cases.
