Hough line transform opencv
Web引言： 霍夫变换(Hough Transform)是图像处理中的一种特征提取技术，它通过一种投票算法检测具有特定形状的物体。该过程在一个参数空间中通过计算累计结果的局部最大值得到一个符合该特定形状的集合作为霍夫变换结果。霍夫变换于1962年由Paul Hough 首次… WebAlgorithm for OpenCV Hough Line Transform. 1. The range for ρ and θ is decided where ρ lies between [-d, d] and θ lies between the range of [ 0, 180] degrees. ‘d’ represents the …
