VCR functionality is difficult to be implemented in a P2P VoD system, since it may give more server workload and fails some distribution paths. In this paper, we first analyze the user behavior of VCR interaction, and propose a video segmentation-aided P2P VoD System with VCR functionality. The simulation results show that our mechanism could reduce the server workload and improve the VCR performance...
A novel algorithm for interactive multilabel image/video segmentation is proposed in this paper. Given a small number of pixels with user-defined (or pre-defined) labels, our method can automatically propagate those labels to the remaining unlabeled pixels through an iterative procedure. Theoretical analysis of the convergence property of this algorithm is developed along with the corresponding connections...
Image mosaic is a very important step in big frame image measurement, its precision has a great effect on the measurement precision. Twice matching can make the mosaic precision beyond the pixel dimensions. And the pixels' gray rebuilding based on pixel position and pixel area distribution also has a great help to raise the measurement precision
