Abstract: To precisely identify a state of an athlete who is present in a swimming pool, a processor used in a device for identifying a state of an athlete or a method for identifying a state of an athlete refers to a result of performing processing of detecting the athlete in a video image obtained by imaging the athlete who is present in the swimming pool and identifies an advancing direction of the athlete as a direction that is different from the previous advancing direction on the basis of a result of the detection of the athlete after the athlete is present in a region on the side of an end of the swimming pool. In this manner, it is possible to more accurately identify the advancing direction of the athlete and to thereby precisely identify the state of the athlete who is present in the swimming pool.

Abstract: In a case in which the size of a moving body changes by a position of the moving body, in order to accurately track the moving body without an effort of the user regardless of a change in the size, the present disclosure estimates a size of the moving body in each of the images of the frames, updates template data based on the estimated size of the moving body, and compares a candidate region that is a candidate of a region where the moving body is present in each of the images of the frames with the template data, and determines whether or not the moving body is positioned in the candidate region based on the comparison result.

Abstract: To provide a motion video segmenting method, a motion video segmenting device, and a motion video processing system that are capable of reducing variation of time required for processing in a case where a motion video is segmented at a predetermined time, and an image processing device performs predetermined processing on a segmented motion video. The motion video segmenting device calculates a load value for each pack based on a rate of an image in which a difficulty degree is high included in the pack, and determines an image processing device having a smallest accumulation value of the load value of the pack which is transmitted previously as the transmission destination when image processing device which is the transmission destination of the pack is determined.

Abstract: A motional state of a player in a video displaying the player in motion is easily determined. This player state display system includes a display device which displays a player video that includes information related to a motional state of the player. A processor generates, based on information that is obtained from an analysis video obtained by capturing the player in motion, a player state display image obtained by visualizing a movement zone corresponding to at least one predetermined motion of the player, and generates, as the player video, a video obtained by superimposing the player state display image on the video including the player in motion.

Abstract: A mobile entity tracking device is provided with: a video receiving unit for receiving a moving-image frame of a ball game captured by each of a plurality of cameras present at different positions; a mobile entity candidate extraction unit for extracting a candidate for a mobile entity using a plurality of moving-image frames; a mobile entity selection unit for displaying candidates for a mobile entity and accepting selection, by a user, of the mobile entity to be tracked; and a mobile entity tracking unit for tracking the mobile entity that is the object to be tracked. When the mobile entity selection unit accepts selection, by a user, of the mobile entity to be tracked, the mobile entity tracking unit corrects the object to be tracked to the mobile entity selected by the user.

Abstract: This ball game video analysis device: receives movie frames captured by cameras; computes the trajectory of the three-dimensional positions of a ball using the received multiple movie frames; determines, on the basis of a change in the ball trajectory, whether or not any action has been made by a player with respect to the ball; in the case when there has been such an action, selects, as an action frame, the movie frame corresponding to the timing at which said action was made; and identifies, from the action frame, a player who made that action.

Abstract: To provide a motion video segmenting method, a motion video segmenting device, and a motion video processing system that increase accuracy of motion video analysis performed by segmenting a motion video. A difficulty degree of each image configuring a pack is determined, and in a case where an image of a difficulty degree of Low continues for a predetermined value F_cnt or more, a motion video is segmented with an image one before a last of consecutive images to form a pack.

Abstract: To precisely specify lane regions that are present in an image. In a situation in which a lane specification device, an imaging device, and a swimming pool are present, a processor in the lane specification device according to the present disclosure specifies lane regions that are present in an image on the basis of a pattern in which information obtained on the basis of outlines of objects in the image captured by the imaging device appears in the image. In this manner, it is possible to precisely specify the lane regions that are present in the image.

Abstract: The present disclosure provides a person tracking method of tracking a person with high precision. According to a person tracking method and a person tracking device of the present disclosure, a processor determines coordinates of a plurality of persons of a video within the video. The processor specifies a group area as an area where the persons of the video are dense. The processor tracks coordinates of a certain person within the video. The processor determines a locus of coordinates of the certain person in the group area based on coordinates of the certain person out of the group area and a number depicted on a clothing.
