Abstract: A rotation state of an object obtained from an input video of a plurality of frames in time series is estimated by using an object image obtained by excluding at least a part of a region common to the plurality of frames from an image corresponding to the object.

Abstract: A target estimation image which is an image of a target at a time point t+w·u obtained by spinning the object in an object image at a time point t obtained from an input video of a plurality of frames in time-series by w unit time on the basis of a hypothesis of spin state and an object image at the time point t+w·u obtained from the input video are used, to estimate the spin state of the object by selecting a hypothesis of spin state and w in which likelihood of the target estimation image becomes high from among a plurality of hypotheses of spin states and a plurality of w whose absolute values are two or more, wherein an absolute value of w is an integer of 2 or more and u is a unit time.

Abstract: Information for displaying information representing rotation axes of balls seen from a first point side or a second point side in regard to one or more motions of the balls moving from the first point side to the second point side is output, and information for displaying information representing rotation axes of the balls seen from an outer side located in a direction that is orthogonal to a virtual straight line connecting the first point to the second point in regard to the motions is output.

Abstract: An athletic performance estimation apparatus evaluates athletic performance from the movement of eyes when observing the movement of a target. A control circuitry (11) selects a measurement condition. A video presentation circuitry (12) presents video according to the measurement condition to an observed person. An eyeball movement measurement circuitry (13) measures the movement of eyes of the observed person who is observing the movement of a target. An analysis circuitry (14) obtains a feature value based on an eyeball movement, from time series information on the movement of the eyes. A normalization circuitry (15) integrates the obtained feature value with a feature value obtained under a different measurement condition and performs normalization. An estimation circuitry (16) estimates the athletic performance of the observed person from a normalized feature value.

Abstract: A performance evaluation device 160 is a performance evaluation device that evaluates a batting performance of a batter in a sport in which balls pitched at various velocities are visually assessed and batted and that includes a performance evaluation unit 169 that evaluates the batting performance of the batter, based on information relevant to movements of the balls obtained as a result of batting of the batter when the balls of a plurality of types of pitch are thrown at random without the batter befog informed of the types of pitch.

Abstract: A synchronization control device receives a trigger signal as input, outputs a first output signal for presenting a specific sensing target of a first sensor at a first time point corresponding to an input time point of the trigger signal, to a first device that presents the specific sensing target of the first sensor, and outputs a second output signal that instructs start of sensing in a second sensor different from the first sensor at a second time point corresponding to the input time point of the trigger signal, to the second sensor.

Abstract: The appropriateness of a motion of a motion actor who makes a motion in response to a motion of at least one moving body other than him/herself is visualized. To display motion information of a motion actor who makes a motion in response to a motion of at least one moving body other than him/herself, an image showing one sequence which is visible or a plurality of sequences which are visible is output. In this case, a relative time which is a position on a relative time axis corresponds to a position on a specific axis of the image. The one sequence or each of the plurality of sequences graphically shows at least a position on the axis which corresponds to a moving body time that is a relative time at which at least one predetermined motion of the moving body was made, and a position on the axis which corresponds to a motion actor time that is a relative time at which at least one predetermined motion of the motion actor was made.

Abstract: The motion performance of an animal that makes a motion in response to the movement of at least one moving body other than the animal, which is a subject for evaluation, is properly evaluated. The motion data of the animal is acquired by manipulating the difficulty factor of the motion which is made by the animal in response to the movement of the moving body, and the motion performance of the animal is evaluated based on the motion data of the animal. It is to be noted that the motion data contains information indicating the timing of the motion of the animal.
