Abstract

In this paper, we proposed a new object-based coding algorithm by using wavelet transform to instead of the image encoder algorithm by using FGS in MPEG-4. The new object-based coding algorithm combines motion estimation with object-based 3-D wavelet transform for video coding in order to fully utilize the redundancy in the time domain. The shape-adaptive algorithm based on modifying boundary extension method of lifting scheme. A sequence of VOPs are fed into the motion compensated lifting (MCLIFT) wavelet coder which first decomposes the VOPs temporarily through MCLIFT filter, and then decompresses the VOPs spatially by shape adaptive lifting wavelet transform (SA-TWT). We encode the video and represent the stream as multilayer bit stream. The integrated transport-decoder buffer ensure the video be continuously transmitted. Losing package can be recovered by using re-transmission.
