【摘要】

：

基于面向特定应用的可配置处理器架构及其设计方法,设计并完成了一种视频媒体编解码片上系统芯片,它具有通用数字信号处理器的柔性编程及特定目标应用时的高性能等特点。该视频编解码片上系统由编码和解码2部分组成,编码和解码部分都采用相同的媒体信号处理架构。媒体信号处理编码、解码架构中分别包含一个8发射超长指令字数字信号处理器核,还包括实现视频媒体应用的专用数据传输单元,变长编解码单元以及接口单元,可以完成H

基于阶层多观测模型的多人行为识别

为解决多人行为识别中高维特征空间、角色分配不准确和复杂的时间结构等问题,本文分析了多人行为的特点,提出了一种递归的多层随机网络模型。该模型通过多层网络表达行为的多尺度特性,并由高层体现行为的长时间依赖性。通过对观测的分解大大降低了特征空间的维数,从而降低了问题的复杂度,并在一定程度上消除了目标角色分配不准确带来的影响。实验结果表明本文提出的模型比其他常用模型具有更好的识别效果,即使对复杂行为依然具
