Random Dithering

Random Dithering is a method of dithering which produces monochrome (black and white) images.

Random Dithering works by choosing a different random value for each pixel in the image. If the pixel is more intense (usually a higher number) than the random value, it becomes white, if not, it becomes black.

Random Dithering tends to produce images with a lot of high frequency noise artifacts (like a badly tuned TV picture), and so is usually not appropriate unless you actually wish to achieve this special effect. However, there are a few cases (generally very simple images with little detail - such as a picture containing a smooth gradient of grays from black to white), where random dithering may actual produce better results than other methods.
