METHOD AND APPARATUS FOR IDENTIFYING VIDEOS BASED ON SHOT FINGERPRINT INFORMATION METHOD FOR PROVIDING ELECTRONIC PROGRAM GUIDE OF ADVERTISEMENTS

摘要

As an operation method of an image analysis apparatus, storing shot information for each target image to be identified in a target image database, receiving a channel image transmitted from a target channel, sequentially detecting shots from the channel image, and Generating fingerprint information, grouping the detected adjacent shots into a similar semantic group and extracting a sub-image composed of a plurality of shots, and a specific target including shot fingerprint information identical to or more than a reference in the target image database Searching for an image, and recording information on a specific target image transmitted from a target channel at a transmission time of a sub-image in a target image transmission timetable. The shot information includes fingerprint information of shots constituting each image.
