Segmentation of Multiple Motions by Edge Tracking between Two Frames
نویسندگان
چکیده
This paper presents a method for segmenting multiple motions using edges. Recent work in this field has been constrained to the case of two motions, and this paper demonstrates that the approach can be extended to more than two motions. The image is first segmented into regions, and then the framework determines the motions present and labels the edges in the image. Initialisation is particularly difficult, and a novel scheme is proposed which recursively splits motions to provide the Expectation-Maximisation algorithm with a reasonable guess, and a Minimum Description Length approach is used to determine the best number of models to use. The edge labels are then used to determine the the region labelling. A global optimisation is introduced to refine the motions and provide the most likely region labelling.

Multi-body Segmentation: Revisiting Motion Consistency
Dynamic analysis of video sequences often relies on the segmentation of the sequence into regions of consistent motions. Approaching this problem requires a definition of which motions are regarded as consistent. Common approaches to motion segmentation usually group together points or image regions that have the same motion between successive frames (where the same motion can be 2D, 3D, or non...
متن کاملComputation of Motion and Occlusion Relation of Objects from the Motion of Their Boundaries
An original approach for motion segmentation using the movement of object boundaries is presented. Our treatment is focused on the case of two motions (background and foreground) and just two frames but can be extended to multiple motions and multiple frames. Segmentation results are presented and some shortcomings of the approach based on global motion models are discussed.
متن کاملFast and automatic video object segmentation and tracking for content-based applications
The new video-coding standard MPEG-4 enables content-based functionality, as well as high coding efficiency, by taking into account shape information of moving objects. A novel algorithm for segmentation of moving objects in video sequences and extraction of video object planes (VOPs) is proposed in this paper. For the case of multiple video objects in a scene, the extraction of a specific sing...
متن کاملEdge Tracking for Motion Segmentation and Depth Ordering
This paper presents a new theoretical framework for motion segmentation based on the motion of tracked region edges. By considering the visible edges of an object, constraints may be placed on the motion labelling of edges. This enables the most likely region labelling and layer ordering to be established, thus producing a segmentation. An implementation is outlined and demonstrated on test seq...

tual reality systems depend on accurate, real-time hand and fingertip tracking for seamless integration between real objects and associated digital information. We introduce a method for discerning fingertip locations in image frames and measuring fingertips trajectories across image frames. We also propose a mechanism for combining direct manipulation and symbolic gestures based on multiple fi...
