Patent ID: 7912284

Claim:
A method of filtering video packets for video stream monitoring comprising the steps of: receiving a video packet of a video stream; extracting one or more features from a specified frame of the video packet via one or more histograms and frequency domain coefficients of the specified frame; implementing one or more concept detectors on the one or more features creating one or more confidence values; and transmitting the confidence values to a display module for filtering of video packets; wherein the extracting step comprises the steps of: parsing the video packet to attain the specified frame; calculating a histogram for each of one or more slices of the specified frame using the frequency domain coefficients of the specified frame; and creating a feature vector of the specified frame based on the one or more calculated histograms; wherein the step of calculating a histogram comprises the steps of: determining frequency domain coefficients of the specified frame; partitioning the specified frame into one or more slices; calculating a histogram of the frequency domain coefficients for each of the one or more slices of the specified frame; and truncating selected frequency domain coefficients in each of the one or more slices of the specified frame.
