Texture-based image colorization using directional sketch
一种基于轮廓提取与纹理分析的图像着色方法*

This paper proposed a novel scribble based method to colorize comic images. The colorization process was guided with the orientation field which was generated from the primal sketch. The pattern-based features were measured by using the statistical feature in Gabor wavelet domain. A variety of results indicate that the directional sketch model provides a straightforward way to present fine details in comic images, and brings significant time savings by propagating colors over various complex texture regions.
