基于图像修复技术的抗核辐射图像恢复方法
A Novel Anti￣nuclear Radiation Image Restoration Algorithm Based on Inpainting Technology
摘要
Abstract
The signal noise ratio of videos and images with digital imaging sensors in strong radiation environment is very low since the digital imaging sensors would be damaged in strong radiation environment due to the impact of high￣energy particles.The quality reduction of image constraints various applications of imaging sensors.In order to remove the noise pro￣duced due to nuclear radiation, a novel anti￣nuclear radiation image restoration algorithm based on inpainting technology is proposed.Firstly,the damaged regions are detected by ana￣lyzing the working mechanism of digital imaging sensors in radiation environment;Then,the damaged regions are repaired with inpainting technology. Finally,the post￣processing based on nonsubsampled contourlet transform of denoising method is performed to improve the vis￣ual quality of the restorated image. The expermental results demonstrate that the proposed method can remove the damaged regions in the source image effectively and further enhance the performances of the camera in strong radiation environment.关键词
