Dithering and halftoning

WebOrder-Dithering-and-Halftoning-Inverse. Image halftoning is one of many techniques to convert a gray or color image to the dot-pattern image. Implemented a simple halftoning inverse method, which aims at reconstructing a continuous-tone image from halftone image of white and black dots. The image can either be black and white or colored. WebIn particular, we propose a Conditional Diffusion model for image Halftoning (CDH), which consists of a halftone dithering process and an inverse halftoning process. By changing the initial state of the diffusion model, our method can generate visually plausible halftones with different dithering patterns under the condition of image gray level ...
