Video Object Wavelet (VOW) Coder

Figure 1. Sample Video Object

We have worked on the compression of arbitrary shape object. We have proposed a new wavelet transform for the arbitrary shape object, and a partial bitplane embedded coder for the compression of the arbitrary shape object. We call the coder the video object wavelet (VOW) coder. Experimental results show that VOW significantly outperforms MPEG-4 in still object coding, and achieves a comparable performance in video object coding in terms of PSNR. Moreover, the VOW decoded object looks better subjectively, with less annoying blocking artifacts than that of MPEG-4.
