Grid Elimination Method for Pulse Images Based on Frequency Domain Processing

Abstract

During the digitized curve extraction process of medical pulse images, to avoid the disturbance of regular coordinate grids for the detection and extraction of the pulse curve, the coordinate grids usually need to be removed before curve extraction. Based on the frequency domain analysis of energy distribution characteristics of the simulated coordinate grids, an approach based on frequency domain filtering is proposed, which can remove grids in the space domain by eliminating the energy components corresponding to the coordinate grids in the frequency domain. The proposed method is proved to be efficient and robust in removing regular grids by experiments.
