摘要:
A method and apparatus for encoding surveillance video where one or more regions of interest are identified and the encoding parameter values associated with those regions are specified in accordance with intermediate outputs of a video analytics process. Such an analytics-modulated video compression approach allows the coding process to adapt dynamically based on the content of the surveillance images. In this manner, the fidelity of the region of interest is increased relative to that of a background region such that the coding efficiency is improved, including instances when no target objects appear in the scene. Better compression results can be achieved by assigning different coding priority levels to different types of detected objects.
摘要(中):
用于编码监视视频的方法和装置,其中识别一个或多个感兴趣区域,并且根据视频分析处理的中间输出来指定与那些区域相关联的编码参数值。 这种分析调制视频压缩方法允许编码过程基于监视图像的内容动态地适应。 以这种方式,感兴趣区域的保真度相对于背景区域的保真度增加,使得编码效率得到改善,包括当场景中没有目标对象出现的情况。 通过将不同的编码优先级分配给不同类型的被检测对象,可以实现更好的压缩结果。
