    Abstract: An information processing device acquiring to the present invention includes: a CPU; and a memory storing a program, wherein the CPU, by the program, configures: a variation-amount calculating unit that, for an input image, calculates a variation amount between a value of a predetermined pixel of the input image and values of peripheral pixels of the predetermined pixel; an attribute reliability unit that, based on an attribute that is a property of pixels within a specified area in the input image and the variation amount, calculates attribute reliability of the pixel; a regularization strength estimating unit that, based on image quality information about image quality for the attribute and the attribute reliability, estimates a regularization strength of the pixel; and an image reconstructing unit generates a reconstructed image that is an image acquired by reconstructing the input image by using the regularization strength.

    Abstract: An information processing device according to the present invention includes: a feature point sampling unit that generates, based on an initial value of a feature point used for registration of an object included in a target image to be processed, a feature point hypothesis that is a group of a plurality of the feature points in the target image; an image degradation unit that generates a degraded image that is a degraded image with degrading a reference image used for processing the target image, based on the feature point hypothesis and a degradation parameter for degrading an image; and a reliability calculation unit that calculates a reliability of the feature point hypothesis, based on the target image, the degraded image, and the feature point hypothesis.

    Abstract: An information processing apparatus may include a memory storing instructions and at least one processor configured to process the instructions to receive an input image. The input image includes either a first image or a provisional image created by iteratively image processing the first image. The instructions further provide for the processor to calculate a local variation of a focused pixel in the input image based on a difference in pixel value between the focused pixel and a surrounding pixel of the focused pixel, to calculate a filter coefficient for suppressing a variation between neighboring pixels in the input image based on the local variation, to create a degraded image by degrading the input image, to calculate a reconfiguration error between the input image and the degraded image, and to create the provisional image based on the filter coefficient and the reconfiguration error.

    Abstract: An input image acquisition unit acquires a plurality of input images in which a specific detection target is captured by a plurality of different modalities. A perturbed image acquisition unit acquires a plurality of perturbed images in which at least one of the plurality of input images is perturbed. A detection processing unit detects a detection target included in the input images using each of the plurality of perturbed images and one of the plurality of input images that has not been perturbed, and acquires, for each of the plurality of perturbed images, a detection position of the detection target and a detection confidence level as detection results. An adjustment unit calculates, based on the detection positions and the confidence levels acquired for the plurality of perturbed images, an adjusted confidence level for each of the perturbed images using integrated parameters.
