Research of Color Image Error Diffusion Method with a New Matching Method

In the paper we analyze the effects of different color spaces to color image dither impact and processing velocity and know that dither processing in RGB space is better judging by quality and velocity of image. A multidimensional element algorithmic method named looking-up table is proposed to make the color matching processing velocity heighten more than one amount degree. So that the required time of image processing is saved. With distances reciprocal as standard, we assign error to four points to make error assign better proportioned.
