Abstract

The invention discloses a detection method and device for similar video files. The method comprises the following steps of obtaining an amount of key frames with the same fingerprint in the first key frames of a first video file and the second key frames of a second video file, wherein a ratio of the amount to the amount of the second key frames is recorded as a first ratio; obtaining the same video fingerprint sequence in the first audio fingerprint sequences of the first video file and the second audio fingerprint sequences of the second video file, wherein a ratio of the range of an audio fingerprint serial number in the audio fingerprint sequence to the amount of audio fingerprints in the second audio fingerprint sequence is recorded as a second ratio, and a ratio of the amount of audio fingerprints in the audio fingerprint sequence to the range of the audio fingerprint serial number in the audio fingerprint sequence is recorded as a third ratio; and according to at least one of the first ratio, the second ratio and the third ratio, judging whether the first video file and the second video file are similar or not. By use of the method, the technical problem in the relevant art that accuracy for detecting the similar video files is low is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for detecting similar video files. Background technique [0002] At present, video similarity detection is widely used in the field of pirated video surveillance. The video similarity detection method in related technologies is mainly based on video key frame fingerprint matching, such as figure 1 As shown, the video similarity detection method in the related art is mainly divided into the following two steps: [0003] 1) Obtain key frame fingerprint features of video a and video b respectively: extract the key frames of genuine video (assumed to be video a) and suspected pirated video (assumed to be video b) respectively, and calculate the color distribution histogram of the key frames, and then Convert the histogram into a fixed-length 0 / 1 sequence, which is the fingerprint feature of a single key frame. [0004] 2) Compare the fingerprint sequences of two video k...
