Ordered dithering - Wikipedia

Ordered dithering is an image dithering algorithm. It is commonly used to display a continuous image on a display of smaller color depth. For example, Microsoft Windows uses it in 16-color graphics modes. The algorithm is characterized by noticeable crosshatch patterns in the result. See more The algorithm reduces the number of colors by applying a threshold map M to the pixels displayed, causing some pixels to change color, depending on the distance of the original color from the available color … See more • Ancin, Hakan; Bhattacharjya, Anoop K.; Shu, Joseph S.

A number of other algorithms are also known; they generally involve changes in … See more Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette. In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels from within the available palette. The human eye perceives the diffusion as a mixture of the colors within it (see color vision). Dithered images, particularly th… cinematic omnisphere presets

WebDec 18, 2024 · Ordered Dithering: This type of dithering process is also used for the conversion of colored images into monochrome. But this process works by choosing a different pattern from the image depending on the color presented in the working area of the image. The below image is the representation of this type of dithering. Original image WebHere we propose an algorithm for data hiding in halftone images. This algorithm uses a morphological operation and ordered dithering, and is a modified version of DHCOD[1].In this paper we focus on improving the security and robustness of shares in VC and generating more meaningful shares with respect to basic cryptographic scheme.
