摘要：
An improved color transfer algorithm was proposed to overcome the limit of the color transfer algorithm based on linear template mapping that just worked well on templates and between dull color images. First, grab cut was introduced for image segmentation, and a region match method based on match vectors was proposed, consisting of region ration, luminance statistical information and color distribution of each regions. Secondly, the correction of color distribution was applied to improve the accuracy of color transfer between small regions, then the nearest point searching method was taken to achieve regional color transfer. Finally, a luminance correction was proposed based on histogram specification to overcome the defect in original algorithm without luminance change. The experimental results show that better details and global color transferring results can be achieved by the proposed algorithm. © 2016, Zhejiang University Press. All right reserved.
