A Study On Image Restoration Method For Magnetic Particle Inspection System

The main idea of this article is about the discussion and research of methods about image restoration in magnetic particle inspection system.Image restoration is a reconstruction or restoration process to the quality declined image through computer.In the image restoration,we first need to establish the degradation caused by image degradation model, and then use the opposite process to restore the original image, last use certain criteria to determine whether get the best restore images.In this paper, first set up the degradation model to study the image restoration method, and use MATLAB to simulation; Then discusse the ringing effect which come out due to the lack of edge image used to smooth the pixels generated in the image recovery process. At last put forward cyclic boundary method to improve the image quality.
