WitrynaSimple Thresholding. Here, the matter is straight forward. If pixel value is greater than a threshold value, it is assigned one value (may be white), else it is assigned another value (may be black). The function used is cv2.threshold. First argument is the source image, which should be a grayscale image. Second argument is the threshold value ... Witryna11 cze 2024 · Image thresholding is a sub-module of image segmentation where certain pixel values are altered according to a particular threshold value where the …
