有人可能会说,边界基准更倾向于contour detectors而不是segmentation methods,因为前者不受产生闭合曲线的约束。因此,我们还考虑了各种基于区域的指标。” 3 检测算法 3.1 mP b 本文是在Martin等人工作基础上提出的多层次版本检测器和新的globalization method,Martin定义了一个函数P b(x, y,

OWT(Oriented Watershed Transform)将上述gPb的结果转换为多个闭合的regions; UCM(Ultrametric Contour Map)将上述regions集,转换为hierarchical tree。 这里出现了很多名词,如:什么是hierarchical tree?什么是Oriented Watershed Transform。 1.1 gPb(Global Probability of Boundary) gPb是mPb和sPb的加权和。 mPb是什么?sPb...

This data set was mainly developed for the evaluation of image segmentation, but it has been widely used for developing and benchmarking contour detection algorithms. Fig. 5a contains examples from these two data sets, while Fig. 5b contains the corresponding hand drawn ground truth binary images...

Object contour plays an important role in fields such as semantic segmentation and image classification. However, the extraction of contour is a difficult task, especially when the contour is incomplete or unclosed. In this paper, the existing contour detection approaches are reviewed and roughly divi...
