The invention discloses a fusion method for video scene segmentation, which comprises: a given video is segmented by using the existing video scene segmentation method to obtain a plurality of candidate scene segmentation results to be used as an input segmentation set of segmentation fusion; a new segmentation is established by using the input segmentation set, and each segmentation point of the new segmentation is pre-processed; if the segmentation point appears in more than half of the candidate segmentations, the point is marked as a true segmentation point; the initial point and end point of a video automatically become true segmentation points; after the true segmentation points are extracted, the new segmentation can be segmented into a plurality of sub segmentation sections; the segmentation points of each sub segmentation section are optimized by optimization algorithm, so that the inconsistency indexes of the finally obtained new sub segmentation sections become as small as possible; and after the optimization algorithm of each sub segmentation section finishes, the result of each sub section is combined to obtain the final fusion result. The invention can effectively segment the scenes forming the video of robust.
Description
technical field [0001] The invention relates to the field of computer application technology, in particular to a fusion method for video scene segmentation. Background technique [0002] With the rapid development of multimedia compression, communication, and storage technologies, as well as the continuous improvement and popularization of Internet software and hardware technologies, the application of digital video has been greatly developed. Facing the ever-increasing mass of video data, how to realize its effective management and retrieval has become an urgent problem to be solved. At present, the most important technologies to solve this problem are video summarization and video retrieval, and a key basic step of these two technologies is video structure segmentation. Decomposing a complete video into a series of meaningful and manageable segments is very important for high-level video summarization and video retrieval. Since a video scene is generally considered to be...
