Robust video retrieval utilizing video data

Patent Number: US20110085734 A1

Publication Date: April 14, 2011

Abstract: Techniques for determining if two video signals match by extracting features from a first and second video signal, and cross-correlating the features thereby providing a cross-correlation score at each of a number of time lags, and finally determining the similarity score based on both the cross-correlation scores.

Robust video retrieval utilizing audio and video data

Patent Number: US 8295611 B2

Publication Date: October 23, 2012

Abstract: Techniques for determining if two video signals match by extracting features from a first and second video signal, and cross-correlating the features thereby providing a cross-correlation score at each of a number of time lags, then determining a mean magnitude of a difference of average values at each of the lags, and finally determining the similarity score based on both the cross-correlation scores and the mean magnitude difference scores, and optionally then outputting an indication of a degree of match between the first and second video signals.
