System and method for detecting video partial copy by using frame feature vector fusion

摘要

The present invention relates to a video partial copy detection system and method. The video partial copy detection system includes: a reference video fingerprint extraction module for extracting fingerprints for reference videos using a fingerprint extractor and storing the extracted fingerprints in a fingerprint DB; a query video fingerprint extraction module for extracting a fingerprint for the query video using the fingerprint extractor; and a copy section detection module configured to measure a similarity between a fingerprint for the query video and fingerprints for reference videos, and compare the similarity to detect a section from which the query video is copied. In particular, the fingerprint extractor according to the present invention extracts feature vectors for frames constituting the video, fuses the extracted feature vectors to extract and provide a segment fingerprint, thereby providing a reference video partially copied from the query video. detect
