Abstract:

Mosaic defect detection is a common phenomenon of video defect in Digital video and will degrade the video quality. Therefore, it is more and more important to locate the mosaic and restore the video. Since the macro block is the smallest synchronization unit in the video image and mosaic is occurred in the form of macro block. A mosaic block detection method based on macro block edge detection is proposed in this study. First, the frame image is processed by canny edge detection algorithm to obtain the edge image. Second, the binary edge image is traversed by macro block and determines the solid edge of macro block; finally the mosaic block is determined according to the number of solid edges on every macro block. The experimental results show that the algorithm has good performance.
