The Hough transform is a feature extraction technique used in image analysis, computer vision, and digital image processing. The purpose of the technique is to find imperfect instances of objects within a certain class of shapes by a voting procedure. This voting procedure is carried out in a parameter space, from which object candidates are obtained as local maxima in a so-called accumulator space that is explicitly constructed by the algorithm for computing the Hough transf… WebPython中的绘图Hough空间,python,python-3.x,computer-vision,edge-detection,hough-transform,Python,Python 3.x,Computer Vision,Edge Detection,Hough Transform,Im使用以下代码在超声图像上生成Hough线： image = mpimg.imread("img.png") data = np.array(image) num_lines = 0 gray_image = …
