A Hybrid Video Coding Scheme Joint Fractal and Object-Based Function

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 macroblock partition scheme instead of classical quadtree partition scheme; reducing the block searching strategy and range, thus increasing the calculation speed greatly; using homo-I-frame like in H.264; reducing repeating calculation, etc. Experimental results indicate that the proposed method can raise compression ratio 4 times, speed up compression time 10 times, and improve the image quality 3 to 5 dB, the proposed object-based scheme improves the performances of fractal video coding algorithm greatly, and the hybrid object-based fractal video coding scheme is simple and effective, it adds more flexibility and practicability of fractal video coding applications.
