<title>Error diffusion algorithm for an arbitrary set of output color with applications in textile sewing</title>

Abstract

This paper describes an extension of bilevel error diffusion technique from one component per pixel (originally gray image), to an arbitrary set of colors, with an arbitrary number of color components per pixel. The binary and multilevel variants of the algorithm are derived as particular cases of the general algorithm. The color set used in error diffusion procedure is selected according to the image that must be reproduced. The error diffusion procedure is investigated with respect to three parameters: size and shape of the local array around the current pixel where the error of color rendition is evaluated, weight mask of errors in local array and the color space where the error distance is computed. The error diffusion procedure is applied and adapted for the designing of the textile sewing process. The original image is resampled corresponding to the resolution determined by sewing process parameters, and the influence of the texture of sewed material is taken into consideration for the simulation process that enables the preview of the final result.
