Digital Video Segmentation Using Level Set Theory
نویسندگان
چکیده
Emerging video coding standards such as MPEG-4 have taken a radical departure from previous video coding standards with the emphasis being placed on content-based functionality and interactivity. Instead of representing video sequences as rectangular arrays of pixels MPEG-4 represents each scene as a composition of video object planes (VOP’s) with each VOP corresponding to one semantically meaningful object. Inspired by recent work on level sets that give excellent results for image segmentation this paper looks at applying them to video segmentation. An overview of level set theory is given. It is shown how level sets can be applied to image and video segmentation. Finally various methods are discussed to reduce the complexity of proposed segmentation techniques.

متن کاملApplying Level Set Theory to Digital Video Segmentation
The emergence of the MPEG-4 standard has brought the area of video segmentation and contour tracking to the forefront or research. In MPEG-4 video sequences are decomposed into various video object planes (VOP’s), which are coded separately into the video stream. This has increased the need for good video segmentation techniques. Inspired by recent advances in level set theory that give excelle...

Over the years, maritime surveillance has become increasingly important due to the recurrence of piracy. While surveillance has traditionally been a manual task using crew members in lookout positions on parts of the ship, much work is being done to automate this task using digital cameras coupled with a computer that uses image processing techniques that intelligently track object in the marit...

In this article, we present a new color image segmentation method, based on multilevel thresholding and data fusion techniques which aim at combining different data sources associated to the same color image in order to increase the information quality and to get a more reliable and accurate segmentation result. The proposed segmentation approach is conceptually different and explores a new str...
