摘要
针对经典基于梯度的边缘检测算法对方向的敏感性,从梯度的定义出发,本文提出了一种能够根据实际精度需求任意调整方向的多方向边缘检测的算法。该算法操作简单,具有图像边缘定位准确,抗噪能力强的特点。
This paper proposes an improved edge detection algorithm based on grad,which aims at the sensitivity of classic edge detection algorithm against directions.This new algorithm can be adjusted to any directions in accordance with the actual requirements of precision,characterized by its easy operation,perfect performance on locating the edge of image and resisting noise.
