Abstract: The present invention enables a high-quality filtered image to be generated even from multimodal and multispectral images containing positional deviations. An image perturbation part generates a perturbed guide image group comprising first to K-th perturbed guide images obtained by deforming a guide image. A filtering part generates a filtered image group comprising first to K-th filtered images by applying first to K-th filtering processing to a target image by using the perturbed guide image group. A reliability calculation part calculates a reliability group comprising first to K-th reliabilities for the first to K-th filtered images of the filtered image group on the basis of first to K-th correlation values between the first to K-th perturbed guide images and the target image. A weight optimization part generates, on the basis of the first to K-th reliabilities, a weight group comprising first to K-th weights to be respectively used when compositing the first to K-th filtered images. An output image compositing part composites an output image from the weight group and the filtered image group.

Abstract: An image processing system in which, in order to easily analyze input images acquired by sensors, output image quality is improved so that is suitable for a user. It includes: a gradient calculation unit that calculates a desired gradient based on input images; an indication function calculation unit that calculates an indication function for the input images, the indication function defining a range that can be taken by an output image and pixel values of a reference image; a pixel value renewal unit that renews pixel values of one of the input images so as to approximate the desired gradient to produce a renewed image; and a pixel value constraint unit that updates pixel values of the renewed image so as to fall within the range that can be taken by the output image and to approximate the pixel values of the reference image, to thereby obtain the output image.

Abstract: An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.
