Halftone dither vs error diffusion

WebJan 19, 2024 · Dithering is a method utilized in pc pics to create the phantasm of color intensity in images with a restrained shade palette. In a dithered picture, shades no longer are restricted to a palette. The human eye perceives the diffusion as an aggregation of the colors inside it. Dithering is similar to the halftone method when utilized in printing ... WebJan 23, 2011 · In this paper, we discussed the traditional methods of generating digital halftoning image and DCT transform. Then we propose a new and simple halftoning algorithm that is based on DCT transformation.
