Web霍夫变换在图像处理里常用来在黑白图像里检测直线,matlab里有相应的几个函数,使用方便,这里把matlab帮助里介绍的例子演示一下。 matlab里霍夫变换主要包含一下三个函数:hough:实现霍夫变换,得到霍夫变换矩阵,用法如下[H,theta,rho]=hough(BW)[H,theta,rho]=hough(BW,ParameterName,ParameterValue)houghpeaks: … WebMar 6, 2024 · The issue stems from the houghpeaks properties being too restrictive to find the smaller lines segments. The approach I used is to: use your current code to obtain the angle that the detected lines are at (I just did [lines.theta] and found that theta will be equal to -84). use again your code but only with that angle included, while relaxing the …
