Abstract
A computer system, method and computer program that retrieves, from at least one piece of moving image data, at least one scene that includes moving image content to be retrieved. The computer system includes a storage unit that stores a locus of a model of the moving image to be retrieved and velocity variation of the model; a first calculation unit that calculates a first vector including the locus and the velocity variation of the model; a second calculation unit that calculates a second vector regarding the moving image content to be retrieved included in the at least one piece of moving image data; a third calculation unit that calculates a degree of similarity between the first and second vectors; and a selection unit that selects, at least one scene which includes the moving image content to be retrieved, on the basis of the degree of similarity.
