Face recognition techniques have been developed significantly in recent years. However, recognizing faces with partial occlusion is still challenging for existing face recognizers, which is heavily desired in real-world applications concerning surveillance and security. Although much research effort has been devoted to developing face de-occlusion methods, most of them can only work well under constrained...
Multi-resolution codes enable multicast at different rates to different receivers, a setup that is often desirable for graphics or video streaming. We propose a simple, distributed, two-stage message passing algorithm to generate network codes for single-source multicast of multi-resolution codes. The goal of this pushback algorithm is to maximize the total rate achieved by all receivers, while guaranteeing...
In order to ease the motion boundary in temporal-domain algorithms, the paper propose to utilize the luminance of macro-block(MB) around the lost MB, to obtain a more precise and dense motion vectors, the rational function be used in motion vector interpolation. Mutation points in the vector field are detected, as a combination of movement of the border, in the same way, the missing pieces of motion...
