Binary thresholding opencv
WebMar 7, 2014 · threshold (image, fImage, 125, 255, cv::THRESH_BINARY); means every value below 125, will be set to zero, and above 125 to the value of 255. If what you are looking for is to have a particular range, for instance 50 to 150, I would recommend you do a for loop, and check and edit the pixels yourself. It is very simple. WebApr 22, 2024 · Thresholding can be performed either with a grayscale image or a colour image. Binary thresholding makes pixel values either to zero or 255 based on the threshold value provided. The pixel values below the threshold value are set to zero, and the pixel values above the threshold value are set to 255.
