| Abstract: | We present a novel video coding system based on the motion compensation and estimation model of H.264 and a hybrid wavelet/matching pursuits image coder for residual frames. After wavelet pre-transformation, a high performance matching pursuits codebook is used to find a series of atoms which are coded by the MERGE coder. The combination of these two techniques produces a highly embedded data stream that can be easily truncated at any desired point. Optimum settings of some key parameters are investigated and a series of experiments are performed. The system works very efficiently and can outperform H.264 at low and medium bit rates. | ||
