Threshold Variation Based on Triangular Probability Density Function for Error Diffusion Halftoning

Abstract:

This paper proposes an error diffusion based halftoning technique of which the threshold is randomly varied to minimize well-known artifacts often observed in the standard method by introducing a triangular probability density function. The diffusion of error is adaptively adjusted depending upon the magnitude of an edge to preserve boundary quality in a half-toned image.
