书籍 The 3G IP Multimedia Subsystem (IMS)

When 3GPP started standardizing the IMS a few years ago, most analysts expected the number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly after that). While those predictions ...

DSP编程 基于DSP与FPGA的多视频通道的切换控制

为了扩大监控范围,提高资源利用率,降低系统成本,提出了一种多通道视频切换的解决方案。首先从视频信号分离出行场信号,然后根据行场信号由DSP和FPGA产生控制信号,控制多路视频通道之间的切换,从而实现让一个视频处理器同时监控不同场景。实验结果表明,该方案可以在视频监控告警系统中稳定、可靠地实现视频通道的切换 ...

技术书籍 LatentSVM论文

The object detector described below has been initially proposed by P.F. Felzenszwalb in [Felzenszwalb2010]. It is based on a Dalal-Triggs detector that uses a single filter on histogram of oriented gradients (HOG) features to represent an object category. This detector uses a sliding window approac ...
