| Abstract(in English) | This paper describes a method of image generation based on transformation integrating multiple differently focused images. First, we assume that objects are defocused by a geometrical blurring model. And we combine acquired images on certain imaging planes and spatial frequencies of objects by using a convolution of a three-dimensional blur. Then, we generate free iris and focus images, including an all-in-focus image corresponding to the pin-hole iris, from the acquired images based on spatial frequency analysis with three-dimensional FFT. Some experiments of image generation utilizing synthesized images and real images are shown and extension of the method integrating multiple differently focused images in the three-dimensional frequency domain is discussed. |
