  • Publication number: 20240104914
    Abstract: A learning model generates a plurality of prototype vectors and generates an integrated similarity vector that indicates similarity between an input image and each prototype for a plurality of prototypes in accordance with similarity between one prototype vector and each pixel vector in a feature map acquired from an CNN. An image processing apparatus obtains prototype belongingness (distributed prototype belongingness) for each image by distributing prototype belongingness of a belonged prototype of each class to each of two or more images that belong to one class. Then, the learning model is subjected to machine learning in accordance with the distributed prototype belongingness of each prototype vector for each image so that each prototype vector is brought closer to any pixel vector in the feature map corresponding to each image.

  • Patent number: 8784864
    Abstract: Bone repair materials are disclosed, from which ions are hardly eluted in living body and which are superior in apatite-forming ability and resistance to apatite peeling and have a scratch resistance high enough for practical use. The material comprises a substrate made of titanium or titanium alloys, and a surface layer, made substantially of titanium oxide, along the surface of the substrate. The substrate has on the surface thereof irregularities of from 1 nm to 10 ?m in average in both width and depth. The layer has a zeta potential of +4.5 mV or more under an aqueous solution environment of pH 6 to 8, and a critical scratch resistance of 35 mN or more when vibration 100 ?m in amplitude is added to a stylus with a spring constant of 200 g/mm on the surface layer and the stylus is moved at a rate of 10 mm/sec under a load increasing at a rate of 100 mN/min.

  • Patent number: 8611604
    Abstract: A depth histogram is created for each of a plurality of local regions of the depth image by grouping, according to specified depths, the depth information for the individual pixels that are contained in the local regions. A degree of similarity between two of the depth histograms for two of the local regions at different positions in the depth image is calculated as a feature. A depth image for training that has a high degree of certainty is defined as a positive example, a depth image for training that has a low degree of certainty is defined as a negative example, a classifier that is suitable for classifying the positive example and the negative example is constructed, and an object that is a target of detection is detected in the depth image, using the classifier and based on the feature.

  • Patent number: 8244323
    Abstract: A method of manufacturing a superconducting tape wire, wherein a reduction in critical current in the superconducting tape wire and the effective AC loss are suppressed. To manufacture the superconducting tape wire, the filaments filled with superconducting material powder and having a flat elliptic or rectangular cross section are disposed in a pipe having a shape whose sides in a pressing direction have a smaller length than adjacent sides, and then the pipe is compressed in the short-side direction to form the pipe in a tape shape.
