  • Patent number: 7899765
    Abstract: A method for measuring tastes, which can better simulate the human gustation than known methods, as well as a taste sensor, computer program and an apparatus for measuring tastes, is disclosed. In this method, data processing is carried out by a two-phase radial basis function neural network. That is, by sensors, each of which sensors can quantify at least one component representing, individually or cooperatively, the taste of saltiness, sourness, sweetness, umami or bitterness, to obtain a response value from each sensor, and each of the obtained response values is input to a first phase radial basis function neural network to calculate the concentration of each component from each response value.

  • Publication number: 20080275315
    Abstract: A major object of this invention is to provide a remote diagnosis apparatus, a remote diagnosis system, a user terminal, a program, a diagnosis program, and a storage for easily diagnosing a pigmentary deposition portion. A user of the system picks up the skin having benign nevus pigmentosus that might be melanoma through a dermoscope using a portable telephone with a camera to which the dermoscope is attached by means of an adapter, accesses to the Internet using an Internet connection function of the portable telephone, and sends the picked up skin image to the remote diagnosis apparatus. After receiving the skin image, the remote diagnosis apparatus uses the melanoma diagnosis program to examine the skin image for melanoma and a disease stage of melanoma if there is melanoma and then sends a result to the user.

  • Patent number: 6816611
    Abstract: A flesh tone region detection processor (12) detects a flesh tone region from a color still image, and a projective distribution generator (13) generates the projective distribution of the detected flesh tone region. A facial region search processor (14) searches the projective distribution for a parabola using, e.g., a genetic algorithm, and extracts a facial region candidate from the position of the found parabola. A knowledge processor (15) checks based on the aspect ratio of the region, matching with facial patterns prepared in advance, or the presence/absence of a region corresponding to hair if the extracted facial region candidate is a facial region. The user can set the processing time, the number of persons to be detected, and the face area ratio as a search end condition.
