Witryna8 sty 2013 · The function cv::distanceTransform calculates the approximate or precise distance from every binary image pixel to the nearest zero pixel. For zero image pixels, the distance will obviously be zero. When maskSize == DIST_MASK_PRECISE and distanceType == DIST_L2 , the function runs the algorithm described in [75] . Witryna7 sty 2024 · Thresholding is the process of converting a grayscale image into a binary image.

Thresholding is a method of image segmentation used to create a binary image from gray-scale or color images. A binary image is an image that has only 2 values, usually black and white, meaning pixels have a value of 0 or 255 . This process is mainly used to separate an object in an image … fit momming
