Hi3516-based Adaptive ROI Coding for Surveillance Video
Author(s): 
Pages: 65-68,96
Year: Issue:  23
Journal: Video Engineering

Keyword:  motion detection;
Abstract: 介绍了基于感兴趣区域(ROI)的智能视频监控编码传输基本原理,以及基于单芯片SoC Hi3516的自适应ROI编码软硬件实现方案.在对Hi3516硬件特性进行介绍的同时,也给出了利用运动侦测功能和其他手段对ROI进行自动检测,以及利用硬件编码通道进行基于H.264的ROI编码和传输方法.实验结果表明,该系统能实时检测视频中的运动目标并进行ROI编码,使得系统在低码率下也能获得很好的图像重建效果.
