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

US Patent: 8,295,611
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.
