Ordered dithering
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.

WebThe Dither extension method is the starting point for dithering a Bitmap in-place, and here are the OrderedDitherer constructor, the strength calibration for the min/max values of the matrix and a fairly fast nearest color search either by RGB channels or by brightness. Share Follow edited Jun 12, 2024 at 20:47 answered Jun 12, 2024 at 20:37 WebOrdered dithering is an image dithering algorithm. It is commonly used by programs that need to provide continuous image of higher colors on a display of less color depth. For example, Microsoft Windows uses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns.
