Patent ID: 7639873

Claim:
A computerized method of automatically detecting one or more segment boundaries in a video, said video including a plurality of video frames, said method comprising: selecting a series of video frames in the video for detection; determining a property value of each of the video frames in the selected series of video frames, wherein the property value of each of the video frames is determined independent of the property value of the other video frames; determining differences of the property values between adjacent video frames of the selected series of video frames; determining a maximum difference of the differences of the property values between adjacent video frames of the selected series of video frames; determining a mean of the differences of the property values between adjacent video frames of the selected series of video frames; determining a ratio of the maximum difference to the determined mean; comparing the maximum difference to a threshold median value and comparing the determined ratio to an adaptive threshold value; and defining a segment boundary as a function of the comparisons.
