Abstract: A computer-vision based automatic inserting and playing method for advertisement analyzes a video for obtaining multiple shots of the video, and obtaining semantic information related to targets appearing in each shot and low-level information related to vision of each shot. Next, the method matches the semantic information and the low-level information of each two adjacent shots with other semantic information and other low-level information of candidate advertisements, so as to determine one or more insertion time points of the video, and one or more inserting advertisements respectively related to each of the insertion time points. The matching of the semantic information ensures the inserting advertisement and a front shot and a rear shot of the insertion time point are all related with each other, and the matching of the low-level information enhances visual fluency in playing and switching among the front shot, the inserting advertisement and the rear shot.
