segment on graph cut

Graph cut segmentationis is segment an image into two classes based on color.

本文通过融合图像的颜色和梯度特征 ,实现了一种实时背景减除方法。首先融合颜色和梯度特征建立新的能量函数 然后基于图切割算法最小化能量函数 ,并对前景P 背景进行分割 最后使用光流验证前景区域的真实性 ,并更新背景模型。-　 Based on the fusion of color and gradient features , this paper implement s a novel approach to real-time background subtraction.Firstly ,

applies normalized cut on graph obtained from image and segment the image into specified number of regions.
