摘要
本文分析了目前图像边缘检测的一些算法和实现方法,并以TMS320DM642EVM作为数字图像处理硬件平台,通过摄像头提取视频序列,利用DM642中IMG_SOBEL库函数进行边缘检测。
This paper analyses some algorithm and realization methods of image edge-detection. The image processing system is based on TMS320DM642EVM,and obtains video sequence with vidicon and then uses lib of function to do the image edge-detection.
