摘要
边缘检测是图像分析识别前必不可少的环节,是一种重要的图像预处理技术。回顾图像边缘检测技术的发展历程,讨论一些典型的边缘检测算法的特点,分析其机理和优劣,并对其中的Canny算法进行优化并通过Open CV实现。
Edge detection is an indispensable step before image analysis and recognition, which is an important technology in the image preprocessing procedure. Chiefly reviews the development of the edge detection methods, discusses the characteristic of some typical edge detection algo- rithms. The Canny algorithm is optimized and implemented with OpenCV.
