首先， 利用基于相位一致梯度与前景标记的分水岭变换进行影 像分割， 提取图像斑块；

The method consists of three steps. Firstly, image segmentation is achieved by watershed transform based on phase congruency gradient and foreground marking to extract image objects.

在几个位置，部分的较暗对象与它们相邻的较亮的邻接对象相融合，这是因为受遮挡的对象没有前景标记。

In a couple of locations, partially occluded darker objects were merged with their brighter neighbor objects because the occluded objects did not have foreground markers.

在美宇航局的威尔金森微波各向异性探测器(WMAP)【3】所获得的数据中，这个算法在宇宙中发现有四个地区，它们标记出有着良好的研究前景。

In data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), the program found four regions in the universe that were flagged as promising.
