  • Publication number: 20180068461
    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.

  • Publication number: 20170236030
    Abstract: An object detection apparatus first sets a first partial region having a preset size and a second partial region in a given point (pixel) in an input image. In addition, the object detection apparatus calculates a first information amount in the second partial region, and sets a third partial region based on the size of the first information amount. Furthermore, the object detection apparatus calculates a score based on a salience degree that is based on a difference in statistical feature amount distribution between the first partial region and the second partial region, and based on an information amount of feature amount in the third partial region. Lastly, the object detection apparatus detects a main object by calculating scores on the respective points in the image and applying a predetermined statistical process to the scores.

  • Patent number: 9714829
    Abstract: An information processing apparatus includes an irradiation unit to irradiate a measurement target with a measurement pattern for distance measurement. An imaging unit obtains a captured image including the irradiated measurement target. A first detection unit detects first and second regions from the captured image. The first region includes a first portion of the measurement target that reflects a greater amount of light toward the imaging unit. The second region includes a second portion of the measurement target that reflects a lesser amount of light toward the imaging unit. A second detection unit detects, from the measurement pattern, a first region with which the first portion is irradiated and a second region with which the second portion is irradiated. A generation unit generates a measurement pattern that has different amounts of irradiation light depending on regions. A distance to the measurement target is derived using an obtained captured image.
