  • Patent number: 11418707
    Abstract: According to one embodiment, an electronic device includes one or more processors. The one or more processors obtain an image captured by a camera with a filter having a first area transmitting light of a first wavelength range and a second area transmitting light of a second wavelength range. The image includes a first color-component image based on the light of the first wavelength range and a second color-component image based on the light of the second wavelength range. The one or more processors notify a user of an effective area for calculation of depth information based on a bias of color information in the first color-component image and the second color-component image.

  • Patent number: 11305428
    Abstract: According to one embodiment, a robot motion planning device includes processing circuitry. The processing circuitry receives observation information obtained by observing at least part of a movable range of a robot. The processing circuitry determines, in a case where first observation information is received, a target position to which the robot is to make a motion, using an action-value function and the first observation information. The processing circuitry receives measurement information obtained by measuring a state of the robot, calculates a difference corresponding to the first observation information, using the measurement information, and determines a motion plan of a force-controlled motion of the robot, based on the target position and the difference.

  • Publication number: 20200159743
    Abstract: An information processing device according to one embodiment includes a first receiver, a second receiver, a first converter, a second converter, and a calculator. The first receiver receives input of first data belonging to a first modality. The second receiver receives input of second data belonging to a second modality that is different from the first modality. The first converter converts the first data into a first representation representing a point or a first area in a D-dimensional vector space (D is a natural number). The second converter converts the second data into a second representation representing a second area in the D-dimensional vector space. The calculator calculates similarity between the first data and the second data by using the first representation and the second representation.
