Abstract: An object tracking processing apparatus includes: an object grouping processing unit that calculates at least one similar object group including at least one object similar to a tracking target object, on the basis of at least a feature amount of the tracking target object; and an object tracking unit that assigns a tracking ID for identifying an object belonging to the similar object group to the object. As a result, the tracking accuracy of the object appearing in a video can be improved.

Abstract: A relationship extracting apparatus acquires event information that indicates features of an event of interest, determine target duration based on one or more features of the event of interest, and extract one or more action-related relationships that exist during the target duration from object relationships information. The object relationship information indicates two or more action-related relationships between objects in association with time at which or during which the action-related relationship exists.

Abstract: A feature extraction apparatus, a method, and a program capable of efficiently using processing resources are provided. In a feature extraction apparatus, a feature extraction unit receives an object image and extracts features of an object included in the received object image. The determination unit determines a value of M (the value of M is an integer equal to or larger than one but equal to or smaller than N), which is the number of object images whose features will be extracted of N object images with which the first tracking ID is associated, in accordance with a usage status of processing resources of the feature extraction apparatus.
