摘要：

Error diffusion dithering is a technique that is used to represent a grayscale image on a printer, a computer monitor or other hi-level displays. For a number of years it was believed that error diffusion algorithms can not be parallelized. On this paper we present a simple error-diffusion parallel algorithm that can be easily implemented on parallel computers that contain linear arrays of processing elements. It can also be implemented easily on specialized hardware. One of the advantages of our algorithm is its low implementation cost, its scalability, and its ability to benefit from standard fault-tolerance techniques.
