Apparatus and method for extracting features of video, and system and method for identifying videos using same
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.
