This paper introduces a 2-D index map coding of the palette mode in screen content coding extension of the High-Efficiency Video Coding (HEVC SCC) standard to further improve the compression performance. In contrast to the current 1-D search using RUN to represent the length of matched string, we bring the block width and height to describe the arbitrary rectangle shape. We also use the block vector...
Utilizing computer aided security risk assessment, administrators can apperceive network security situation quickly and take countermeasures effectively. Most assessment methods disregard the dependencies among services, lack the evaluation against indirect risks, and seldom mention the composition of multiple source risks. Regarding the above problems, an assessment method that based on service dependency...
A new algorithm named ant colony optimization with multiple nestspsila cooperation (MNACO) is presented to resolve the narrow traveling salesman problem. The union suppose and intersection suppose based on MNACO are proposed. The black, white and grey edges are defined. The edges in the intersection (black edges) are deposited certain pheromones. The white edges are deleted and the grey edges in the...
