ROI soccer video compression using wavelet-domain block matching and EBCOT coding techniques in very low bit rate communication

Today, a large amount of sport video data are produced which needs to be stored and/or transmitted in low bit rate applications such as internet communication. The Region-of-interest (ROI) video coding technique aims to relatively preserve the video quality, especially in desired regions. In other hand, in soccer videos only special regions have importance for the viewer. In this paper a novel ROI soccer video compression method is proposed which employs wavelet-domain block matching, shot boundary detection, Enhanced EBCOT coding, and region-of-interest detection techniques. The compression performance of the proposed method is compared to that of two conventional methods/standards of MPEG4 and FLV. Simulation results show that in fixed low bit rate of 8Kbps, the proposed method has about 1.5 dB higher average PSNR than that of the other ones.
