WitrynaBinary thresholding. A very simple method of segmentation consists in associating with each pixel of the image f a binary number which depends on the intensity of the pixels and on a threshold (French: seuil) T: g ( m, n) = { 1 if f ( m, n) ⩾ T, 0 if f ( m, n) < T. This method is called “binarization” (French: binarisation ). WitrynaImage segmentation is one of the most critical image processing techniques. Image segmentation is to divide the target pixels with the same features into the same area and divide the target pixels with different characteristics into different areas [1,2].Image segmentation performs an important role in medical image processing, and it is …
