| Abstract(in English) | Many methods for restoring images degraded by noise or blur use one noise image or blurred image. BM3D as a typical noise elimination method, and BM3DDEB as a blur removal method. In recent years, a restoration method using a plurality of noise images and blurred images obtained by photographing the same scene a plurality of times has been proposed for the restoration method dealing with these single images. In this paper, we assume the latter case and perform image restoration using two types of images: image restoration using two noise images and noise image blurred image. By taking a weighted average of two noise images or a noise image and a blurred image, a weighted average image including useful image information possessed by each deteriorated image is obtained. We show that image restoration with higher precision can be realized than BM3D or BM3DDEB on these weighted average images, compared to using only a single image . |
