Implementation and analysis of MPEG-4 dynamic resolution conversion

Requirements for effective way of storing multimedia content are continuously increasing. Many compression techniques have been developed, but harsh compromise between coding efficiency and decompressed content quality still has to be made. Although that compromise is inevitable, techniques are being developed that can help lower the bit rate while still retaining the decompressed content quality. This paper discusses implementation and analysis of one such method - dynamic resolution conversion, that was introduced in version 2 of MPEG-4 standard.
