Based on these excellent characteristics of Phase Congruency Model, we use it to detect the edge of natural image.
基于这些优良特性，本文采用相位一致性模型对图像进行边缘检测。
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.
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；
