Hiromi Shiozaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10540609
    Abstract: To precisely predict future data even when the number of pieces of time-series data is small, in predicting the future data, using the time-series data. When the future data is predicted using the time-series data, whether present time data is used is determined based on prediction variation or a data transition, and then the prediction of the future data is performed.

  • Patent number: 10380759
    Abstract: The present invention aims to estimate a more consistent posture in regard to a multi-joint object. A target range image is first input, a human body region is extracted from the input range image, a target joint position candidate is calculated from the input range image, and a joint position is finally determined based on the calculated joint position candidate and a likelihood of each joint to estimate the posture. At this time, joint position permissible range information concerning inter-joint distance and angle of a human body model previously set by learning is obtained from a human body model storing unit, consistency is evaluated for a relation between the joint position candidates of a certain joint and other joint based on the obtained information, and thus the posture corresponding to the best combination of the joint positions is determined.

  • Patent number: 9531969
    Abstract: An image processing apparatus includes an extraction unit, a setting unit, a reference value calculation unit, a comparison unit, and an information determination unit. The extraction unit extracts a target area from an image. The setting unit sets a pixel from the target area as a pixel-of-interest. The reference value calculation unit calculates a reference value based on a pixel value of at least one or more pixels included in the target area. The comparison unit repeatedly performs processing of comparing a pixel value of at least one or more pixels among a plurality of pixels in a predetermined layout with respect to the pixel-of-interest with the reference value. The information determination unit determines information of the pixel-of-interest based on a comparison result of the comparison unit and a value corresponding to the comparison result.
