Abstract:
1. A method of characterizing digital video data with arbitrary image edges contained therein, the characterized video data is then stored in an image edge database for rapid matching of video streams, said method comprises: receiving a digital video data stream; segmenting the received video data stream into at least one frame of pixel information; detecting and determining one or more image edges using an edge filter applied to the pixel information; calculating Hu invariant third moments for each of the detected image edges, wherein said each of the detected image edges is assigned a unique identifier based on the Hu invariant third moments; converting the calculated Hu invariant third moments into a set of integer indices based on a set of predefined criteria; and storing the unique identifier of said each of the detected image edges into an image edge database with a database location in reference to the set of integer indices.
