Abstract: Through analysis and study of non-photorealistic watercolor rendering methods and features，this paper proposes a non-photorealistic method of watercolor simulation based on multi-structure and multi-scale color morphology.During the process of achieving its edge darkening and patterns flowing，it designs a new combination of structures such us ring，circular and diamond by taking advantage of the color morphology’s open and close，the expansion and corrosion operator theory.The effective simulation of non-photorealistic watercolor is finally realized by using various sizes of multi-structure elements and different spatial scales of image feature and operating in different colored models.The result of the experiment shows that this method simulates the unique artistic effect of non-photorealistic watercolor successfully.
