单基因信号被认为是解析信号从一维空间向高维空间的推广，在文献中受到了相当大的关注。它由原始信号及其各向同性希尔伯特变换（Riesz变换的组合）定义。与解析信号类似，单基因信号可以写成极坐标形式。然后给出了局部衰减和局部相位矢量等信号特征的表示。本文的目的有两个：首先，分析高维空间中局部相位矢量与局部衰减之间的关系。其次，研究了基于改进差分相位一致性的图像边缘检测方法。与实际图像上的竞争方法进行比较，一致地显示了所提出方法的优越性。
Monogenic signal is regarded as a generalization of analytic signal from one dimensional to higher dimensional space, which has been received considerable attention in the literature. It is defined by an original signal with its isotropic Hilbert transform (the combination of Riesz transform). Similar to analytic signal, the monogenic signal can be written in the polar form. Then it provides the signal features representation, such as the local attenuation and the local phase vector. The aim of the paper is twofold: first, to analyze the relationship between the local phase vector and the local attenuation in the higher dimensional spaces. Secondly, a study on image edge detection using modified differential phase congruency is presented. Comparisons with competing methods on real-world images consistently show the superiority of the proposed methods.
