Broadcast video logo detection and removing

Video logos can be considered as a form of visible watermark which is a trademark or symbol to declare the video copyright. However, in some cases, it will cause visual discomfort due to the presence of multiple logos overlapped directly or blended with another logo in videos. In this paper, we use an efficient gradient-based average approach to detect the logo firstly; then, the selected logo mask in the entire video sequence will be inpainted by the spatial-temporal image restoration technique. Experimental results show that our method is capable of recovering various kinds of video logos in the visually plausible way.
