Abstract:
An embodiment relates to performing error concealment of a corrupted block in a video frame, which is capable of performing a real time reconstruction of corrupted blocks which allow to precisely recover small details and fine movements, in particular, the error concealment apparatus and method according to an embodiment selects a replacement block by taking into account the luminance distortion and the motion characteristics of the video sequence. The latter is represented by the distance of the motion vectors chosen as candidate replacements and the average value of the motion vectors of the blocks surrounding the missing block in the current frame.
