Color Photo Makeover via Crowd Sourcing and Recoloring

It is not always easy for amateur photographers to capture photos with desired colors even on a classic hot spot as the appearance of color photo dependent on many factors. This paper proposes a novel approach to recolor given photos via a crowdsourcing based makeover scheme. When a user input a photo to be recolored, the proposed system will first conduct favorite exemplars suggestion from the images hosted by the social media sites, by jointly leveraging contextual and visual information associated with the images. The recommended exemplars shall reveal the scene and context dependent color compositions and provide users with diverse possible color styles. Then, a novel superpixel-based recoloring scheme, incorporating color statistics, texture characteristics and spatial constraints into soft matching, is applied to generate new photos of desired color. Experiments and a user study demonstrate that the proposed color photo makeover is able to achieve robust recoloring results for various outdoor photos.
