Blind Computer X-ray Imaging System (cr)-based Medical Image Restoration Method Of Research

This paper introduces the fundamental principle of X-ray image, and analyzes the reason of common blur. Then establishes the context of this paper—investigate the blind restoration of X-ray image. According to explicit and detailed inquisition on current blind restoration technique, a novel framework of blind restoration was proposed.At the first stage, the blurred image was pre-processed via multi-frame average, then de-noised via mean filter. At the second stage, the parameters of PSF was estimated by a cepstrum method. In the end, On the comparison of several popular filters, constrained least square (CLS) was adopted to restore the blurred image.
