Abstract

In this paper, a method of half-edge composite structure (HECS) extraction is proposed. First, an edge is divided into two half-edges, and then one half-edge is combined to form a HECS according to the condition. A HECS is an infrastructure composed of two half-edges and one endpoint. Matching means to calculate the distance between the HECS description vectors of two images and to get high-quality matching according to the conditions. To describe a more complete image structure, we propose a graph structure combination method based on a HECS. The feature set of the graph structure is formed by the association of the HECS, and the matching relationship of the graph structure set is mapped by the matching results of the HECS. Based on the image structure set and visual residual phenomenon, a motion matching model of video stream is constructed, which is called the visual residual model. For numerical estimation of natural images, we propose an evaluation method to investigate the feature stability of video images. The result shows that performance of the algorithm discussed in this paper has a good performance in the numerical estimation of continuous matching feature stability shown in the video stream.
