Dithering
Dithering is a technique used to apply noise to an image in such a way that it tricks the human eye, improving the final quality. This implementation contains two versions, Floyd-Steinberg's and Omohundro's.
Usage
Both functions take two parameters, a grayscale image and the number of shades of gray to perform dithering.
f = floydsteinberg(img, 4);
figure; imshow(uint8(f));
o = omohundro(img, 4);
figure; imshow(uint8(o)); Floyd-Steinberg |
