Web阈值处理可以用来从图像中剔除低于或高于一定值的像素，其基本的思想是，给定一个数组和一个阈值，然后根据数组中的每个元素的值是低于还是高于阈值而进行一些处理。OpenCV 提供了 cv::threshold() 操作来进行阈值处理：
WebStandard Hough Line Transform. First, you apply the Transform: vector lines; HoughLines(dst, lines, 1, CV_PI/180, 100, 0, 0 ); with the following arguments: dst : Output of the edge detector. It should be a grayscale image (although in fact it is a binary one) lines : A vector that will store the parameters ( r, θ) of the detected lines. iom business nameWebThe Hough transform is a feature extraction technique used in image analysis, computer vision, and digital image processing.
