Fast and automatic video object segmentation and tracking for content-based applications

Changick Kim, Jenq-Neng Hwang
2002 IEEE transactions on circuits and systems for video technology (Print)  
A novel algorithm for segmentation of moving objects in video sequences and extraction of video object planes (VOPs) is proposed in this paper.  ...  After removing edge points which belong to the previous frame, the remaining edge map, moving edge (ME), is used to extract the VOP.  ...  Since spatial edge information is useful for generating VOP with accurate boundaries, a simple binary edge difference scheme may be assumed to be a good solution.  ...

Changick Kim, Jenq-Neng Hwang
2002 IEEE transactions on circuits and systems for video technology (Print)  
Once a VOP is extracted, the shape of the VOP needs to be well described.  ...  In such a framework, the concept of a "key frame" is replaced by that of a "key video-object plane (VOP)."  ...  in the luminance difference [see Fig. 1 Fig. 2 shows the block diagram of our segmentation algorithm.  ...
