摘要：
A method of characterizing a video by providing index information includes the steps of extracting representative frame images from an input video, calculating a feature of each of the representative frame images, assigning respective codes to the representative frame images, each of the codes being determined by the calculated feature of the representative frame image to which the code is assigned, generating a code string by stringing together the codes assigned to the representative frame images, and storing the code string as index information of the input video.
