MATLAB Online에서 열기 In your code, you are trying to access values like BW(i-1,j) so wheni=1this becomesB(0,j). In MATLAB index zero is not allowed. Therefore you are getting the error the subscript must be a real positive integer. ...
基于Canny算子的边缘检测———MATLAB 一、概念 Canny算子是一种非常重要的边缘检测算子,是最优的阶梯型边缘检测算子。它的最优性主要表现在以下三个方面; 好的检测:Canny算子可以尽可能多地标识出原始图像中的实际边缘。好的定位:它所标记出来的边缘尽可能给你地接近实际图像中的实际边缘。 最小响应:图像中的边...

边缘检测是图像处理的主要组成部分。尽管基于卷积神经网络等基于深度学习的技术可以执行非常复杂的边缘检测(即具有变化的曲率,噪声,颜色等的边缘),但在某些情况下,经典的边缘检测方法仍然具有很高的意义!例如,如果已知数据是简单且可预测的;与CNN相比,Canny边界检测可以立即使用,而CNN的实现通常较为复杂。
