Abstract
Systems and methods for concealing video errors encountered in a frame of a static or moving image that can be used independently or in combination with conventional error concealment techniques, and can be used to conceal an error segment of any shape or location in a frame of a static or moving image. An error segment is identified. A first pixel set adjacent to the error segment and optionally one or more other pixel sets also adjacent to the error segment are selected corresponding the pixel set of the error segment and are flipped toward the error segment. The flipped pixel sets are then selectively weighted. Where only one pixel set is used, the flipped and weighted pixel set replaces the error segment to conceal the error segment. Where more than one pixel set is utilized, the pixel sets are added together to create a sum pixel set that replaces the pixels of the error segment to produce a smooth transition between the error segment and the adjacent, non-corrupt sets of pixels without any distracting boundaries. The smooth transition diminishes the visual impact of the error segment in the frame of the static or moving image.
