摘要
利用图像的图表示定义了一个衡量区域间边界存在性的谓词函数,在此基础上给出了一种运行时间与图中边的数目成近似线性,实际效果良好的有效图像分割方法。方法具有在高可变性区域时忽略细节,在低可变性图像区域时保存细节的能力.
A predicate for measuring the evidence for a boundary between two regions using a graph - based representation of the image was defined. Based on it, we propose an efficient image segmentation method. Its running time is nearly linear in the number of graph edges and is also fast in practice. This method has the ability that preserving detail in low- variability image regions and ignoring detail in high - variability regions.
