Novel Video Error Concealment Using Shot Boundary Detection

Abstract

AbstractThere are two conventional approaches for error concealment, i.e. the temporal approach and the spatial approach. Normally temporal error concealment is preferred due to its low computational complexity and good image quality after error concealment. However, the temporal error concealment will become ineffective for the frames at the shot boundary since the content of the frame is much different from the reference frame before the shot boundary. To address this problem, in the paper, we propose a novel error concealment method. First, a real time shot boundary detection method is proposed to detect whether the current damaged frame is at the shot boundary or not. Second, if the frame is at the shot boundary, the spatial error concealment method is adopted to conceal the damaged frame; otherwise, the temporal concealment method is adopted. Experimental results show that the proposed method is efficient, effective in fine concealed image quality, and accordingly quite suitable for kinds of video players.
