Looks in a box (width x height) around the pixel neighborhood if the pixel value is bigger than the average minus an offset. WitrynaThresholding is one of the most basic techniques for what is called Image Segmentation. When you threshold an image, you get segments inside the image... each representing something.

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.
