| Abstract(in English) | DCT-based coding schemes have been successfully applied to the compression of still and moving images, such as JPEG and MPEG standards. A major problem related with the DCT techniques is that the decoded images, especially at low bit rates, exhibit visually annoying blocking effects. To reduce such artifacts, various schemes based on low-pass filtering have been proposed. Combination of ε-filter and weighted median filter is one of powerful filter for reducing the block artifacts. In this paper, we implement the combination filter on DSP (TMS320C6416:C64). C64 has 8 processing elements and VLIW architecture. We realize super-parallel processing and 8 outputs are obtained at same time. Only 10msec is necessary for processing the 1024×768 pixels. |
