Abstract :
This paper mainly describes the high quality image compression system using modified motion vector detection for the multi-directional stereo imaging system. The data rate of high resolution imaging system would exceed more than several Gbits/sec, and the multi-directional imaging system furthermore increases the above data rate. Accordingly, the large grade of data compression should be indispensable in the transmission of high spatial multi-stereo imaging data. The paper proposes the new compression method based on the modified motion vector detection and applying JPEG2000 [Taubman, D.S., et al., 2002] and JPEG-LS [Taubman, D.S., et al., 2002; Sayood, K., 2000] compression methods. The paper reveals the effectiveness of the averaging of the motion vector between the successive multi-stereo imaging data. As the results, the paper shows the proposed method is superior to ordinary JPEG2000 or JPEG-LS in the quality of signal to noise ratio, and can reduce the data rate to less value than conventional compression method.
