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 ... WebJun 6, 2024 · cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 31, 2) There are two adaptive methods for calculating the threshold value. While Adaptive Thresh Mean returns the mean of the neighborhood area, Adaptive Gaussian Mean calculates the weighted sum of the neighborhood values.

WebSep 27, 2024 · The threshold value is the approximate value of the middle of these two peaks. If the image is not bimodal this thresholding is not accurate. To apply Otsu’s thresholding, we apply simple thresholding cv2.threshold() with extra flag cv2.THRESH_OTSU. See the syntax given below.
