Fast Fingerprint Retrieval with Line Detection

A fingerprinting system for video copy detection

“…[4], which employ a pairwise boosting on a large set of Viola-Jones features [12], to extract audio fingerprints by learning compact, discriminative, local descriptors on audio spectrograms [4], we has proposed a video fingerprint method, which employ a modified pairwise boosting on visual Viola-Jones features [12], to learn topdiscriminative filters for video fingerprinting [5] [6]. The top four Harr features learned for video fingerprint's extraction are shown in Fig.…”

“…2 without copyrights are collected by editors of a web site, these videos are decoded/encoded and preprocessed into a common format by steps as described in section II. The video fingerprint extraction method is used to extraction fingerprints from videos and then the fingerprints are loaded as references to build hash tables for the retrieval of copyright detection system by using a direct hashing algorithm [4] [6]. On the other hand, users upload their videos to the web sites.…”

“…The decision is made by using a minimum criterion among retrieval scores of segmentations, which means that the most similarity between segmentations and references will determine whether a video uploaded has copyright or not. The retrieval score of a segmentation is obtained by conducting a segmentation into video fingerprinting retrieval system, which adopting a direct hashing algorithm [4] [6], and then returning the most similar score.…”

“…The goal of fingerprinting is to provide fast and reliable methods for content identification [1] [2][3] [4]. Promising applications of video fingerprinting are filtering filesharing services, broadcast monitoring, automated indexing of large-scale video archives, etc [2][5] [6].…”
