The lower bound is attainable only by images having a single gray level, and the upper bound is attainable only by ... The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity is less than a fixed value called the threshold , or a white pixel if the pixel intensity is greater than that threshold. In the example image on the right, this results in the dark tree becoming completely black, and the bright snow becoming completely white.
WebJul 20, 2009 · In image processing, Otsu’s thresholding method (1979) is used for automatic binarization level decision, based on the shape of the histogram.
