| Abstract | ||||
| This paper describes a computationally efficient hybrid video coding scheme. The proposed hybrid coding scheme combines the advantages of simple hardware complexity of the 3-D discrete cosine transform coding and the high performance of the 3-D set partitioning in hierarchical tree (3-D SPIHT) coding. The modification of the subband video data in the wavelet domain is done based on the DCT transformation and the classification of the coefficient in the low-frequency video subband (LL). The modification process provides a new subband video data containing almost the same information of the original one but having smaller values of the wavelet coefficient. Simulation results of the proposed method demonstrate that, with a small addition in the computational complexity of the coding process, the PSNR performance of the proposed algorithm is much higher than that of the 3-D SPIHT test coder. | ||||
