Before starting, make sure the "Results" window is closed. A variable is a placeholder for a changing entity. 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.
