  • Publication number: 20230394733
    Abstract: A processing device includes an acquisition unit that acquires an instruction to specify a conscious behavior of a target that reproduces a behavior of a user, a determination unit that determines a parameter for reproducing an unconscious behavior corresponding to the conscious behavior specified by the instruction from unconscious parameter data in which an identifier of a conscious behavior of the user, an identifier of an unconscious behavior in the conscious behavior, and an index for specifying a parameter for reproducing the unconscious behavior are associated with each other, and an output unit that outputs a determined parameter to a drive unit TD of the target T, in which a parameter for reproducing the unconscious behavior varies depending on the conscious behavior.

  • Publication number: 20230108075
    Abstract: A behavior classifier includes a coordinate estimation unit that receives a plurality of frames in chronological order as an input to estimate a keypoint coordinate group for each of the plurality of frames and to generate a chronological keypoint coordinate group for the plurality of input frames; a matrix generation unit that generates a trajectory matrix and generates a trajectory matrix group in which trajectory matrices are collected for all of keypoints defined for the object; and a behavior classification unit that classifies a behavior of the object based on the trajectory matrix group. Each of the plurality of frames captures an object as a moving image. The keypoint coordinate group is a set of two-dimensional coordinates of a keypoint defined for the object. The chronological keypoint coordinate group is a set of the keypoint coordinate groups arranged in chronological order.

  • Patent number: 7359547
    Abstract: The pseudo depth information of a subject is generated from multiple images of the subject captured with and without illumination or under various illumination intensities. A pseudo 3D image generating apparatus generates a pseudo 3D image. It includes an image storing unit that stores the images, and a depth computing unit that computes pseudo depth values of the subject based on operations between the pixel values of corresponding pixels in the images. A compact and handy 3D image generating apparatus is provided.
