Abstract

A video search device extracts a plurality of objects each contained in a different one of frames of a video, assigns a weight value to each of the extracted objects based on a time-series feature of the frame containing the object, and searches for an object similar to each of the extracted objects based on the extracted objects each having the weight value assigned thereto.

Description

technical field [0001] The present invention relates to a technique for searching for related objects, images, and the like based on objects appearing in images. Background technique [0002] In recent years, the storage capacity of digital video recorders has increased due to multi-channel broadcasting and the start of video distribution services for Internet TV. [0003] In addition, a storage device for storing large-capacity images is arranged in a server on the network to store / view images. Along with this, the practical use of a search device for efficiently selecting a desired video from a large number of videos stored in a storage device has been advanced. [0004] In Patent Document 1, designation of an object (person) included in a certain frame of video is accepted from the user, and the feature value of the accepted object is extracted. Then, by using the extracted feature value for comparison, other video scenes in which the accepted target object appears are ...
