摘要

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.
