Foreground editing technique to reduce interaction

In this paper we introduce a method to extract foreground from an image or a video and blend it into another environment. We analyze the weakness of previous algorithms, and propose a new method to improve the automaticity of the algorithm and reduce interactions with users. Self-adaption threshold and segmentation technique are used to preprocess the images or frames. And then we use the image matting and illustration technique to refine the segmentation results. Our method is also suitable for video editing to reduce the users operation. The experiment demonstrates that our algorithm can be used under several challenging scenarios.
