Abstract

We propose an artistic recoloring method that enhances the perception of complex scenes, while preserving the visual quality of the original image. Our algorithm employs the template which contains the information of color theme. The colors of template is selected based on the Munsell color and are designed on the a 驴驴驴 b 驴驴驴 chromatic plane of the CIE L 驴驴驴 a 驴驴驴 b 驴驴驴 color space. Template can be used to recolor the original image with simpler and more focused color contrasts. The proposed algorithm consists of the three steps. First, we calculate the regression line for the colors on the original image and the template. Then we create a transformation refer to the relationship between the two regression lines. This transformation is used to change the color distribution in the source image. Finally, the transformed color distribution is mapped from the chromatic a 驴驴驴 b 驴驴驴 plane to become the template.
