Abstract: By analyzing both the strengths and weaknesses of the color space of RGB,LSH,L^*a^*b^*,this paper puts forward a new order of color vector,which focuses on RGB colorspacith a combination of the revised distance order and lexicographical order.Basic operators of color image morphology are established.The result of the experiment demonstrates that the color vector order has good property.The algorithm of color image morphology based on this order can better keep the peripheral information and hue of the image and has the strong point of unnecessity of exchanging between different color spaces.

Key words: color space, vector order, mathematical morphology, dilation, erosion
