    • A method executed by a computer system for detecting edges comprises receiving an image comprising a plurality of pixels, determining a phase congruency value for a pixel, where the phase congruency value comprises a plurality of phase congruency components, and determining if the phase congruency value satisfies a phase congruency criteria. If the phase congruency value satisfies the phase congruency criteria, the computer system categorizes the pixel as an edge pixel. If the phase congruency value does not satisfy the phase congruency criteria, the computer system compares a first phase congruency component of the plurality of phase congruency components to a phase congruency component criteria. If the first phase congruency component satisfies the phase congruency component criteria, the computer system categorizes the pixel as an edge pixel, and if the first phase congruency component does not satisfy the phase congruency component criteria, categorizes the pixel as a non-edge pixel.
    • 由计算机系统执行的用于检测边缘的方法包括:接收包括多个像素的图像,确定像素的相位一致值,其中相位一致值包括多个相位一致分量,以及确定相位一致值是否满足 阶段一致性标准。 如果相位一致值满足相位一致性标准,则计算机系统将像素分类为边缘像素。 如果相位一致值不满足相位一致性标准,则计算机系统将多个相位一致分量的第一相位一致分量与相位一致分量标准进行比较。 如果第一相位一致性分量满足相位一致分量标准,则计算机系统将像素分类为边缘像素,并且如果第一相位一致分量不满足相位一致分量标准,则将像素分类为非边缘像素。
