Abstract
A method for detecting whether query video data appears in a reference video, comprising determining a measure of depth from a portion of the query video data, comparing the measure against a measure of depth for the reference video to perform a depth match and, if a match is determined; comparing a visual signature derived from the query video data against a visual signature of the reference video to perform a visual match to determine a measure representing the likelihood that the query video data derives from the reference video.
Claims19
A method for detecting whether query video data appears in a reference video, comprising:
- determining a measure of depth from a portion of the query video data;
- and
- comparing the measure against a measure of depth for the reference video to perform a depth match and, if a match is determined, comparing a visual signature derived from the query video data against a visual signature of the reference video to perform a visual match to determine a measure representing the likelihood that the query video data derives from the reference video.
A copy detection system for a 3D reference video, comprising:
- one or more processors providing an execution platform including copy detection modules, the modules comprising:
- an extraction engine to determine a measure of depth from a portion of query video data;
- and
- a comparison engine to perform a depth match by comparing the measure against a measure of depth for the reference video and to perform a visual match by comparing a visual signature derived from the query video data against a visual signature of the reference video to determine a measure representing the likelihood that the query video data derives from the reference video.
A computer program embedded on a non-transitory tangible computer readable storage medium, the computer program including machine readable instructions that, when executed by a processor, implement a method for detecting copied portions of a reference video, comprising:
- determining a measure of depth from a portion of query video data;
- and
- comparing the measure against a measure of depth for the reference video to perform a depth match and, if a match is determined, comparing a visual signature derived from the query video data against a visual signature of the reference video to perform a visual match to determine a measure representing the likelihood that the query video data derives from the reference video.
