This process is also known as inverse halftoning. Different values of σ simulate what the eye sees from different distances. On the left σ = 1, on the right σ = 2: 4.2. Direct binary search

WebIn an algorithm called Riemersma dithering, grayscalephotograph can be converted to a ditheredblack-and-white image using thresholding, with the leftover amount from each pixel added to the next pixel along the Hilbert curve. WebHere is the pseudo code for the dithering algorithm from this Wikipedia article, on which my code is based on.. And here are the variable explanations: M(i, j) is the threshold map on the i-th row and j-th column, c′ is the transformed color, and r is the amount of spread in color space.

http://dictionary.sensagent.com/riemersma%20dithering/en-en/ WebFeb 5, 2012 · The dithering is coarser, but has fewer visual artifacts. It is slower than Floyd–Steinberg dithering because it distributes errors among 12 nearby pixels instead of 4 nearby pixels for Floyd–Steinberg. Stucki dithering is based on the above, but is slightly faster. Its output tends to be clean and sharp.
