摘要

Image matting is the extraction of the foreground from an image through the use of provided information. It has been an important technique in the image and video editing field. Current image matting methods estimate the foreground and background, based on information provided regarding the nearby pixels. Color sampling has been an effective means for matting directly, and quite a few methods have achieved high quality matting results based on color sampling. However, there are some drawbacks; for example it is easy to overlook important candidate pixels for matting, and even if the candidate pixels are effectively selected, similar foregrounds and backgrounds will reduce the accuracy of the matting.
