- A NEW ACCORDION BASED VIDEO COMPRESSION METHOD. SUNKARA, JAYA KRISHNA; PURNIMA, KURUMA; SUBBAREDDY, L. RAMA; SAGARI, E. NAVANEETHA // Journal on Electrical Engineering;Jun-Aug2011, Vol. 1 Issue 4, p14
Usually, a video signal has high temporal redundancies due to the high correlation between successive frames. This redundancy has not been exploited enough by current video compression techniques. In this paper, the authors present a new video compression technique which tends to hard exploit...
