Problems solved by technology

Although the implementation of data-driven segmentation is simple, it ignores the structural changes in the video. If the threshold is not selected properly, the gradual switching process of the video lens such as fade-in and fade-out will be missed.

Abstract

The invention discloses a monitoring video motion fragment segmentation method based on visual perception energy, and relates to the technical field of an image processing method. The method comprises the following steps that the side surface of a monitoring video sequence is extracted at the boundary of moving in and out of a visual monitoring area of a moving target, and target deformation on the video side surface is analyzed and a VPE curve is established; the inflection points of the VPE curve are detected and the positive and negative energy inflection points are processed; statistics of the VPE of all the positive energy inflection points and the corrected VPE of the negative energy inflection points is performed, and a cumulative VPE curve is drawn; and monitoring video motion fragment segmentation is performed according to the cumulative VPE curve, wherein the VPE refers to visual perception energy. According to the method, the accuracy of monitoring video motion fragment segmentation is enhanced and the video data volume requiring processing is greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing methods, in particular to a monitoring video motion segment segmentation method based on visual perception energy. Background technique [0002] The structuring of the video is to divide the video data stream hierarchically on the time axis, and complete the conversion from the original unstructured video stream to the structured video entity. Divide the original video stream into meaningful and easy-to-manage video structural units to form a hierarchical structure of video content, which facilitates the analysis and management of video content. [0003] Video is an unstructured data stream, which is essentially a series of temporally continuous image frames. These image frames only have a temporal relationship to each other without any structural information. Video segmentation is to detect hierarchical structural units from digital video sequences according to video content or...
