Patents
Pixel Forensics, Inc. strongly believes that while pushing the technical
envelope, we will make discoveries that others have not made. When these
events occur, we take a lot of pride in applying for patents from these
discoveries. To date, we have received approval for two patents, are in
the process of applying for others and have additional novel technologies currently in development.
Robust video retrieval utilizing audio and video data
Issued 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.
