Wavelet transform based video content extraction for 3D wavelet video coding

In recent years 3D wavelet video coding has become a popular research area due to its low coding complexity. As the emerging MPEG-4 video compression standard places a strong emphasis on content base manipulation and compression, there is a need to implement the content coding feature within the 3D video coding algorithms. In this paper we propose a very simple algorithm to separate the foreground and background pixels for content based video coding. This algorithm exploits the 3D wavelet transform characteristics and only adds as small amount of overhead to the existing 3D video compression algorithms.
