When we approximated the colors from one palette to another, the difference in the color introduced in the pixel is called quantization error. Dithering is applying noiseto the image to distribute these quantization errors. Take a simple example of gray rectangle (grayscale value 100). Mapping the rectangle to binary, … See more An image can be rendered on a computer screen using millions of colors. In a traditional bitmap, every pixel is represented by a … See more Let's start with a simple case - a binary image where each pixel is either black or white. In a grayscale image each pixel can have a value between 0-255. For a binary image, if the value is closer to white (>=128), use white, … See more Two common ways dithering are Ordered and Error Diffusion. Ordered dithering is based on a fixed matrix and is localized — a pixel's value does not influence the dithering of surrounding pixels. Read more about it here. In Error … See more Take a moment to try the interactive demo at the top of this page with ditheringOFF. You will notice that the output is not quite as attractive.
