Local color editing using color classification and boundary inpainting

Color Editing plays an important role in image processing, which aims to change the original image color according to specific image color characteristics. We present a new interactive local color editing method. The user first draws strokes specifying the target region needed to transfer color, which can be segmented using K-means clustering. Then patch-based inpainting technology is applied to achieve natural transition along the boundary. In the course of color editing, only the color of the pixels in this segmented region is transferred, while others including the boundary region and the background remain unchanged. The experimental results show that our method can achieve a visually satisfying local color editing results.
