The invention provides a method and device for detecting video image matting tampering. According to the method and device for detecting video image matting tampering, abnormal edge detection is conducted on a video image, deviation in the four directions of each edge point is calculated, and then a more accurate tampering detection result is obtained. Furthermore, after a tampered object is determined, learning is conducted on the tampered area in a frame of the tampered object, and then an object tracking algorithm is applied to each following frame; in this way, tediousness caused by the fact that abnormal edge judgment is conducted on each frame is avoided, the efficiency of obtaining the tampered frames is effectively improved, and the time complexity of running is greatly reduced.
Description
technical field [0001] The present invention relates to a video image processing method, in particular to a video matting detection method and device. Background technique [0002] Today, with the rapid development of network and multimedia technology, the dissemination of multimedia files such as pictures, audio and video becomes faster. The emergence of high-quality imaging equipment and advanced multimedia editing software in the digital age also makes it easier to edit and tamper with such data. While the advancement of technology has brought convenience to people, it has also brought some adverse effects. Maliciously tampered videos are disseminated through the Internet, confusing the public, disseminating false information, and some criminals destroy evidence through tampering with the video, which undoubtedly affects social stability to a certain extent. Therefore, in the field of information security, video tampering detection technology has become a research hotsp...
