Abstract
Abstract By sequentially inputting images for each frame, sequentially extracting features from the inputted frame images, converting the features sequentially extracted into a feature series corresponding to the inputted frame image series, compressing the feature series in the direction of the time axis, storing the compressed feature series in the storage, sequentially extracting features separately from the images to be retrieved for each inputted frame, sequentially comparing the features of the images to be retrieved for each frame with the stored compressed feature series, storing the progress state of this comparison, updating the stored progress state of the comparison on the basis of a comparison result with the frame features of the succeeding images to be retrieved, and retrieving image scenes matching with the updated progress state from the images to be retrieved on the basis of the comparison result between the updated progress state and the features of the images to be retrieved for each frame, the present invention can retrieve video images on the air or video images in the data base at high speed and enables self organization of video to be classified and arranged on the basis of the identity of partial images of video.
