Parallel Dithering: How Fast Can We Go ?
Abstract
From palette reduction in GIF images to printing, dithering techniques are widely used. With the increasing size of the images today, due to better photographic hardware, we can wonder if we can gain in performance by processing an image in parallel. In this paper, we will implement a MPI algorithm to apply the Floyd-Steinberg dithering in parallel. We will then focus on performance and look for optimal values of parameters.
