说明：  本文提出的图像分割技术和自然图像抠图算法应是合理的树木图像特征相结合。一个准确，快速，实时提取工艺树的形象设计是今后研究的重点和难点问题。
(This paper proposes that image segmentation technique and natural images matting algorithm should be reasonable combined for tree image features. The design of an accurate,rapid, real-time tree image extraction technology is the focus and difficult problem in future research.)
