The method first triangulates the source image based on its lo- cal details, to emulate artists’ methods of observing and analyzing the image structures. Then, it converts the color from the source image to obtain the fuzzy color for every triangle. Finally, it renders the triangles by a customiza- ble fuzzy coloring strategy to emulate artists’ painting methods. The results show that the proposed method achieves good simulation of different artists’ coloring strategies. Using the rendering application based on the proposed method, the user can quickly achieve many renderings in different coloring strategies by our mosaic rendering prototype.
