Abstract
Currently, most of the existing algorithms about mosaic video detection are complex and time-consuming, suitable for off-line video. For real-time video, fast and simple mosaic detection is important. This paper proposes a kind of mosaic template matching strategy for fast detecting mosaic defects in real-time video. First, we analyze the feature of mosaic edge image and preset some templates of mosaic block. Secondly, we use the Canny edge detector algorithm to get the edge image, and then pre-process it in the horizontal and vertical directions. Finally, we detect the mosaic point of intersection with the template matching strategy. The experimental results show that the proposed method can efficiently and quickly detect the mosaic image, which has actually been implemented on probation in a TV station.
