Edge detection methods based on modified differential phase congruency of monogenic signal

Abstract: 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). Like the analytic signal, 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:… Show more

“…The second algorithm is called the QDPC method, which is motivated by the study of Felsberg et al Felsberg et al applied the scale derivative of the local phase angle of the 1D intrinsically monogenic scale function (Hardy function in the upper half complex plane) to obtain the DPC method for the edge detection problem, while Yang et al applied the scale derivative of the local phase vector (non 1D intrinsically monogenic scale function) …”
