The restoration of radiograph with an improved power spectrum equalizer

Scattering is the main factor which influences the sensitivity of X-ray radiographic system. After studying the mechanism of image degradation, analyzing the advantages and disadvantages of power spectrum equalizer, and combining with the power spectrum estimation of the typical images, the authors put forward an improved restoration method on power spectrum equalizer. The practical results show that this method can depress the blur of the image, and effectively preserve the edge informations of radiograph.
