This paper deals with all-in-focus image reconstruction by merging multiple differently focused images. We previously proposed a method of generating an all-in-focus image from multi-focus imaging sequences based on a 3-D filtering. In this paper, we first combine the sequence into a 2-D image. Just by applying a 2-D filter to the image, we realize fast reconstruction of all-in-focus images robustly...
This paper describes a method of image generation based on transformation integrating certain sequences of multiple differently focused images. First, we assume that a scene is defocused by a geometrical blurring model. Then we combine spatial frequencies of the scene and the sequence with a 3-D convolution filter that expresses how the scene is defocused on the sequence. The filter can be represented...
