WebThe threshold in OpenCV helps in assigning pixel values. These pixel values are allocated to threshold values. These values are then compared with the threshold values and the image is segmented by setting this value to maximum if pixel value is greater than threshold and if less then it is set to 0. To segment the image this technique is most ... Webretval, threshold = cv2.threshold(img, 10, 255, cv2.THRESH_BINARY) A binary threshold is a simple "either or" threshold, where the pixels are either 255 or 0. In many cases, this would be white or black, but we have left our image colored for now, so it may be colored still. The first parameter here is the image. only way to stop smoking permanently
