摘要
近年来,随着DSP技术的快速发展,数字视频处理技术得到了越来越广泛的应用。边缘检测是是数字视频处理中的一项关键技术,而且是进行对象检测和识别的基础。本文首先分析了当前发展比较成熟的几种边缘检测算法,然后针对基于DSP的数字视频处理系统的特点选用Laplacian of Gaussian(LoG)边缘检测算法,并在基于DM642的数字视频处理系统上实现,给出了仿真的结果。
In recent years, with the rapid development of DSP technology, digital video processing techniques have been applied more and more. Edge Detection is a key technology in digital video processing and it is the foundation of object detection and recognition. In this paper, several edge detection algorithms are analyzed, and Robert edge detection algorithm is realized on DM642-based digital video processing system. The simulation results are given finally.
