| 摘 要： | 为得到更加精确的图像分割结果，可以在基于图割的分割框架中引入形状先验指导分割。针对矩形目标提出了一种目标/背景交互式分割方法。分割能量用马尔可夫随机场最大后验概率描述，通过限制有向图中的流向引入形状先验，可以保证图割优化后的分割结果为矩形形状。对仿真图像与真实图像的实验结果证明了该算法的有效性。

| Abstract: | In order to obtain more robust result, shape prior is incorporated into segmentation framework as an efficient constrain. This paper proposed a novel object/background segmentation algorithm for rectangle shaped objects. The rectangle shape prior was imposed by restricting flows towards valid directions in the digraph. The segmentation energy was formulated by MAP-MRF. Firstly introduced the concepts of LineCut and ParaCut, and then described RectCut in detail. Experimental results demonstrate the effectiveness of the method. |
