Classical linear signal processing techniques, when applied to color demosaic, tend to over smooth the color signal. This results in noticeable color artifacts along the edges and sharp features. Such techniques, like color filter array (CFA), which each light sensor is covered by one kind of filter.....

The major part of multimedia applications (such as video conferencing and digital TV broadcasting) is video processing due to its high encoding complexity. The objective of current advanced video standards (including H.264 and AVS) is to achieve higher coding efficiency. In order to meet the objecti.....

LDA is a popular feature extraction technique for face recognition. However, it often suffers from the small sample size problem when dealing with the high dimensional face data. Fisherface and Null Space LDA (N-LDA) are two conventional approaches to address this problem. But in many cases, thes.....

Photonic band gap (PBG) materials are those periodic composites that possess spectral gaps in the frequency spectrum, in which electromagnetic waves cannot propagate in any direction within the material. Conventional PBG are based on Bragg scattering which limits the size of PBG structures for low-f.....

Previous merging algorithms have un-practically high computational complexity and hence cannot be applied to medium or large size networks. This invention presents two fast algorithms to merge anonymous routers. The first one uses Isomap to embed routers into a high-dimensional space based on their .....
