Interactive image recoloring by combining global and local optimization
2016
We propose a novel interactive image recoloring method by combining global and local optimization. Our approach assumes that each pixel is a linear transform of its neighbors which can be in spatial or feature space. Corresponding, a new framework for combining global and local energy optimization is designed and derived. By taking advantage of global and local color propagation, our approach requires only a few user scribbles to produce the high-quality results. We show various experimental results and comparisons on image recoloring. Compared with the state-of-the-art methods, our approach produces higher-quality results with only a small amount of user interaction than those only consider local propagation or global propagation approaches.
