The Target In The Research And Application Of Interactive Video Segmentation Algorithm

With the development of computational intelligence, computer vision technologygain more and more researchers’ concerne, there also has spawned many related areas ofapplication development, such as interactive video technology based on content, ofwhich the key techology is video object segmentation. Video object segmentation is thebasis for numerous applications such as video encoding based on the content, videosurveillance, human-computer interaction, and high accuracy segmentation of videoobject can greatly reduce the difficulty of subsequent applications.Interactive video technology is an innovative application with constant innovationand development of the Internet and multimedia technologies, it has altered thetraditional video mode that makes videos for users not only to watch, but also forfurther interaction with the user.This application model is a new attractive userexperience model, so far, there have been many interactive video-related products in theeducation industry, advertising, entertainment, film and television industry,andachieved much development and success.Based on the above background, this thesis made some research work on this fieldof video object segmentation algorithm, especially focus on video object segmentationby hypergraph-cut. And based on the algorithm, the thesis propsed a improvedmechanism for the algorithm, which achieving effective results. The main content ofthis article and invonation poits is followed by:(1) Video object segmentation by hypergraph-cut, which is a video objectsegmentation algorithm based on spatio-temporal domain. Based on the algorithm, thispaper presents a improved method by assigning larger weights to the hyperedges. Thenthis thesis do a comparative experiment and data analysis to compare the improvedalgorithm with the original algorithm, proved that the improved algorithm proposed inthis thesis slightly better than the original algorithm on the segmentation performance.(2) Based on the above improved method proposed, this thesis designed andimplemented an interactive video system based on object segmentation. UsingDirectShow technology to realize a capture filter for video frame. And followed by the introduction of the implementation of the filter for frame capture, the implementation ofobject segmentation and the management for the object contour. Finally, the thesistested the system with some video data, and analysed its function and shortage.
