Abstract:
1. A method for video detection comprising: (a) receiving an input video signal; (b) creating a temporal sliding window of initial length L seconds, and capturing at least a first portion of the input video signal with the temporal sliding window; (c) comparing a first segment of the first portion of the input video signal captured by the temporal sliding window of initial length L seconds to a portion of stored fingerprint data; (d) expanding the temporal sliding window to have an expanded length approximately equal to the length of the stored fingerprint data if the first segment of the first portion of the input video signal matches the portion of stored fingerprint data; and (e) comparing a second segment of the input video signal captured by the expanded window having the expanded length with the stored fingerprint data.
