- W2103264562 abstract "In this paper, the impact of scene change on the conventional error concealment method is addressed and a novel error concealment method is proposed to improve the insufficiency of the conventional temporal error concealment algorithm due to the occurrence of scene changes. Combined with the low complexity scene change detection algorithm using macroblock type information, the corrupt blocks resulting from bit errors are concealed either temporally or spatially depending on whether or not an abrupt scene change is found. In the case of a gradual scene change, a novel error concealment method of interpolation and extrapolation is proposed to utilize the linear property of a gradual scene change sequence, and effectively reduce the concealment error compared with the conventional algorithm. A great improvement of about 3 to 5 dB PSNR is obtained with only small memory and computation overhead." @default.
