Floyd steinberg dithering演算法
WebSep 8, 2024 · Floyd-Steinberg dithering nicely preserves contrast and details, and it even produces something similar to smooth gradients, even with a very limited palette of two colors: Figure 3: Floyd-Steinberg produces the best result of the three methods discussed in this article. Note how most of the detail and contrast is preserved. WebFloyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg. It is commonly used by image manipulation software, for example when an image is converted …

WebFeb 21, 2024 · The Floyd-Steinberg algorithm is relatively simple. It scans the image one pixel at a time, scanning the top line from left to right, then the next line, etc. until it reaches the bottom. For a bitonal dither, it's easier if we first convert the whole image to grayscale, so that each pixel has a luminosity (perceived brightness) value of 0 to 255.
