WebApr 28, 2024 · The cv2.threshold function then returns a tuple of 2 values: the first, T, is the threshold value. In the case of simple thresholding, this value is trivial since we manually supplied the value of T in the first place. But in the case of Otsu’s thresholding where T is dynamically computed for us, it’s nice to have that value. WebRegion growing. Region growing is a simple region-based image segmentation method. It is also classified as a pixel-based image segmentation method since it involves the selection of initial seed points . This approach to segmentation examines neighboring pixels of initial seed points and determines whether the pixel neighbors should be added ...
