With a rapid demand for multimedia information, visual information plays an important part in information achieving. But the data size of a video is so enormous that it should be compressed and coded immediately. In order to improve the efficiency of MPEG-4 and MPEG-7 adopt content-based coding method, a video sequence is segmented into several meaningful video objects before coding. Video object...
Based on the classical fractal video compression method, an improved monocular fractal compression method is proposed which includes using more effective macroblock partition scheme instead of classical quadtree partition scheme; using improved fast motion estimation to increase the calculation speed; using homo-I-frame like in H.264, etc. The monocular codec uses the motion compensated prediction...
Based on the classical fractal video coding scheme, a novel hybrid video coding scheme joint fractal and object-based function is proposed. A new technique of object-based fractal video coding in which each object can be encoded and decoded independently results in increasing compression ratio and speed and reducing bit rate and bandwidth is used. The proposed techniques include: using more effective...
