An object tracking device stores, for each site of an object, information indicating an area image of the object in a first frame image of frame images included in a moving image, and stores a conspicuous site of the object. In response to the object being lost, for each maximum value position in a conspicuity map for a second frame image with the lost object, a recovery unit in the object tracking device (1) estimates an area with each site of the object when the conspicuous site is hypothetically at the maximum value position and (2) calculates a similarity score based on a similarity between the area image of each site in the first frame image and the area image of each site in the second frame image, and determines that the object is at a maximum value position in the second frame image with a maximum similarity score.

Object tracking device and object tracking method

In a watching assistance system that assists watching over a subject on a bed, a region setting unit performs processing of receiving a region setting image captured by an imaging device, specifying an approximate position of the bed from the region setting image by object detection, and specifying a bed region by extracting a contour of the bed from a local range including the approximate position.

Monitoring assistance system, control method thereof, and program

A watching assistance system that assists watching over a subject on a bed includes an image acquisition unit configured to acquire an image captured by an imaging device, a criterion storage in which a criterion for determining a dangerous state are previously set for each of a plurality of determination regions set based on a region of the bed in the image, a detector configured to detect the subject from the image acquired by the image acquisition unit, a state recognition unit configured to recognize a state of the subject detected by the detector, a determination unit configured to determine a danger degree of the state of the subject recognized by the state recognition unit using the criterion for the determination region corresponding to a position at which the subject is detected by the detector, and an output unit configured to provide notification according to the danger degree determined by the determination unit.

A watching assistance system that assists watching over a subject on a bed, the watching assistance system includes: a detector configured to detect a position of a predetermined region of the subject from the image captured by an imaging device; a determination unit configured to determine whether the subject raises oneself up based on the position at which the predetermined region of the subject is detected; and an output unit configured to provide notification when the determination unit determines that the subject raises oneself up. Based on a bed region in the image, a lying region is set to an existing range of a predetermined region at a lying time, and a raising-up region is set to an existing range of the predetermined region at a raising-up time. The lying region and the raising-up region are disposed at an interval. The determination unit determines that the subject raises oneself up when a condition that predetermined region of the subject is detected in the raising-up region after the predetermined region of the subject is detected in the lying region is satisfied.
