Methods, devices and computer program products facilitate the extraction of embedded watermarks in the presence of content distortions. Subsequent to the detection of a tentative watermark, particular sections of the content are examined to form one or more extrapolated watermarks or watermark segments. Weights are assigned to the extrapolated watermarks or watermark segments, and used in combination with the detected tentative watermark to collectively assess if a desired probability of false detection is satisfied.
