摘要： An apparatus for extracting features from a video includes a frame rate converter for performing a frame rate conversion on the video to a preset frame rate, a gray scale converter for performing a grey scale conversion on the frame rate-converted video, a frame size normalizer for performing a frame size normalization on the gray scale-converted video to a preset image size, and a feature extractor for partitioning the normalized video into image blocks of a predetermined size, and extracting features from the image blocks on the basis of luminance values of the image blocks. A video identification system employs the feature extracting apparatus to identify an original video and an object video.

摘要： An index database creating apparatus includes a feature extracting unit for extracting features from a content; an index creating unit for creating feature indices of the extracted features; an index selector for selecting one or more of the feature indices based on frequency-based importance levels thereof; and a feature index database for storing therein the selected feature indices along with locations thereof in the content. The index selector obtains the frequency-based importance levels based on frequency distributions of the feature indices in the content and in other contents to be stored in the feature index database.

摘要： Disclosed is a system and method for tracing illegally copied contents on the basis of fingerprint. Purchaser information is inserted into digital contents that include image, audio or video data using a fingerprinting system when the digital contents are sold in the distribution process of the digital contents. If the contents purchaser has illegally copied and distributed the contents through the Internet or a P2P (Peer to Peer) server that is a file sharing server, the corresponding contents are searched for using a searcher and the corresponding purchaser is traced on the basis of fingerprint information inserted into the contents.
