  • Patent number: 11055877
    Abstract: A gradient calculation unit calculates an image gradient on a pixel-by-pixel basis in each of a plurality of images. A scale search unit calculates a scale score based on degree of spatial frequency components for each pixel in each of the images. A gradient score calculation unit calculates, for each pixel, a gradient score on the basis of the image gradient and the scale score. A gradient finalization unit calculates, using the gradient score and, as a target gradient, an image gradient of each pixel in a combined image. On the basis of the target gradient, a coefficient calculation unit calculates, for each pixel of the combined image, a coefficient of base vectors constituting a preset base vector group in the combined image. A combining unit generates the combined image through linear combination of the base vectors based on the calculated coefficients.

  • Publication number: 20210174231
    Abstract: Disclosed is a model generation device capable of mitigating the risk of overlooking a phenomenon of interest in machine learning. The model generation device determines whether or not a label of a first data is similar to a label of a second data. The model generation device assigns the label of the second data to the first data when determining that the label of the first data is similar to the label of the second data based on a degree of similarity between observation information representing a state where the first data is observed and observation information representing a state where the second data is observed. The model generation device calculates model representing a relevance between data information containing the first data and the second data and label information containing the assigned label and the label of the second data.
