Video tracking and processing system based on dual-cored architecture
摘要
提出一种基于ADSP-BF561的视频跟踪与处理系统设计方法。系统利用ADSP-BF561的双核并行处理性能和丰富的视频编解码接口,采用一种相关跟踪算法对其进行优化,算法是一种以相关系数作为相似性度量准则的相关跟踪算法。对该系统进行测试,结果表明:针对PAL制目标视频图像序列,系统可以实现复杂背景下的实时目标跟踪,视频目标跟踪对每帧的处理时间为22 ms,解决了目标跟踪的实时性要求。
Abstract
A design of video tracking and processing system based on ADSP-BF561 was proposed. This system took full advantage of the excellent performance of dual-core processing and the profile interfaces of encoding and decoding. The paper used a correlation tracking algorithm based on correlation coefficient. And many measures were put forward to improve the speed of the algorithm, in order to satisfy the requirement of object real-time tracking. The experiment result based on the target video in phase alternating line (PAL) shows that the method can achieve object tracking in a complicated background in real time.
