Color Halftoning Using the Error Diffusion Method by the Edge Adjustment and the False Colored Limit

In the device that the usable number of the colors and density of printer or facsimile communication are limited, the digital halftoning is an important technique. When you use error diffusion method for mix of color and monochrome images, false color appear in monochrome parts. The images were evaluated using the Mean Squere Error. The image evaluation of MSE had rise. And so the evaluation with the monitor, a very good value was in this way provided. Full-color images grayscale is not contaminated and black and white images, images of the experimental results of different patterns, without compromising the quality of the original error diffusion method, we solve the problem.
