Abstract: This paper proposes a novel color editing algorithm for complex natural images with repeated scene elements, which can be recolored quickly and accurately with less user interaction. Firstly, some regions of the input image can be marked by color scribbles, and the input image is divided into several superpixels by using SLIC (simple linear iterative clustering) algorithm. Secondly, a robust distance is defined to measure the similarity among     repeated scene elements based on the constructed feature space. Finally, color information is assigned based on the local feature similarity, then they can be propagated to the whole image by color editing. The experimental results show that the proposed algorithm not only improves the efficiency of color editing, but also gets high quality results with coherence and consistency.
