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...
On the basis of some research work about the educational evaluation index system of electronic games,we establish an educational evaluation system for electronic games using BP neural network model.The system has self-learning and adaptive characteristics.After the BP neural network trained with the expert knowledge,it not only has the experience of experts, but also realizes the changes from the...
It's necessary to create a credible and general evaluating index model in network threat assessment. According to the network indices' effect, this paper proposed an algorithm which combines grey correlation degree in grey theory with traditional analytic hierarchy process (AHP) to determine the indices. It considered both objective and subjective factors. Experiments showed that this method had a...
Due to resource constraints, digital image transmissions are a significant challenge for image sensor based wireless sensor networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called image component transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Essential components such as the information for the positions of significant...
