-View of the current large-scale P2P systems can not effectively deal with malicious nodes to attack the problem, the paper presents a new risk assessment based on credibility and trust model of P2P system, the model taking into account the impact of the dynamic behavior of nodes trust the calculation of uncertainty, the introduction of risk factors, and to make use of information entropy theory to quantify the risks, will be the degree of trust between the entities and trust uncertainty unified. Simulation and analysis show that the trust model can effectively identify the malicious node, compared to some of the existing trust model to a greater extent to improve the system the rate of successful transactions, you can make between nodes more effectively to establish a relationship of trust.

Description: 运动估计是视频编码的关键技术，其最基本的原理是利用相邻帧间的时间
相关性，通过预测来减少时间冗余度。在实际编码中，为了节省码率，并不传
输每一帧的全部数据，而是利用运动估计求出每一帧与其预测参考帧之间的差
值。运动估计越准确，差值的分布越趋近与零，差值块的能量越小，经过变换、
量化和熵编码后所产生的码流的比特位率也越少。因此，运动估计搜索的准确
程度直接影响到了编码的压缩性能。
-Motion estimation is the key to video encoding technology, its basic principle is the use of the adjacent time frame relevant, through the forecast period to reduce redundancy. In the actual code, in order to save bit rate and does not transfer all the data of each frame, but the use of motion estimation for each frame obtained with the prediction of the difference between the reference frame. Motion estimation more accurate, more closer to the margin and the distribution of zero, the smaller the energy difference between blocks, after transform, quantization and entropy coding of the code produced by the bit stream bit rate is less. Therefore, the motion estimation search accuracy of the direct impact on the performance of the compression coding.
