Image restoration in computed tomography: restoration of experimental CT images
IEEE Transactions on Medical Imaging, 1992It is pointed out that to restore experimental computed tomography (CT) images which have been blurred by a spatially variant point spread function (PSF), a quadrant symmetry method which simultaneously optimizes storage requirements for the estimated PSFs and computational speed is used.

General restoration filter for vibrated-image restoration
Applied Optics, 1998Mechanical vibrations are often the principal cause of image degradation. Low temporal-frequency mechanical vibrations involve random image degradation that depends on the instant of exposure. Exact restoration requires the calculation of a specific filter unique to each vibrated image.

Image restoration in radioisotopic imaging systems
Physics in Medicine & Biology, 1967In radioisotope image visualization, the final image must be interpreted by the human visual system. However, an inherent blurring of the image limits the amount of useful information which can be extracted from it. Attempts have been made to restore the image by compensating for the degradation.

U²-Former: Nested U-Shaped Transformer for Image Restoration via Multi-View Contrastive Learning
IEEE transactions on circuits and systems for video technology (Print)While Transformer has achieved remarkable performance in various high-level vision tasks, it is still challenging to exploit the full potential of Transformer in image restoration. The crux lies in the limited depth of applying Transformer in the typical
