Image watercolorization based on visual weight-map

This paper presents a watercolor rendering technique that recreates the artistic effects. Visual features make focused object apply different simulation value. The method is organized in two steps: Image abstraction based on the weight-map; Detail verisimilitude of watercolor features. Verisimilitude includes color space conversion, boundary region diffusion, morphological smoothing, and adding texture. In experiments, amount of color images were processed for promoting reality. The result indicates this method is more efficient and suitable for image watercolorization.
