Abstract: In this paper, we propose a method of capturing multimodal images in a single shot by attaching various optical filters to the front of a light-field (LF) camera. However, when a filter is attached to the front of the lens, the result of capturing images from each viewpoint will be a mixture of multiple modalities. Therefore, the proposed method uses a neural network that does not require prior learning to analyze such a modal mixture image to generate an image of all the modalities at all viewpoints. By using external filters as in the proposed method, it is possible to easily switch filters and realize a flexible configuration of the shooting system according to the purpose.
