Previous image segmentation methods are mainly based on region or contours. The former category of models are computationally expensive, while the latter approaches require lots of user interactions. In this paper, we propose a novel interactive image segmentation method, which makes a combination of the two models. By adopting the advantage of respective models, our method can produce high quality segmentations with little user interaction and achieve a surprisingly high efficiency.

Then we refine the boundary region on finer scales using active contours based method iteratively. The experimental results show that our method can produce better segmentation results to state-of-the-art while greatly reducing user interactions and processing time. We believe the proposed method could greatly improve user experiences in real applications. Figure 1: Examples of interactive image segmentation. (a) Original images.
