WebWith this perspective, this work introduces methods to mitigate disruptive effects of widely deployed H.264 and H.265 video compression standards on PRNU estimation. Our approach involves an intervention in the decoding process to eliminate a filtering procedure applied at the decoder to reduce blockiness. Webtured by that imaging sensor. The procedure for extracting PRNU noise has been well studied in the context of photo-graphic images, however, its extension to video has so far been neglected. In this work, considering H.264 coding stan-dard, we describe a procedure to extract sensor ﬁngerprint from non-stabilized videos. The crux of our method ... WebSep 1, 2009 · A majority of recent researches about PRNU-based source device attribution for digital videos do not take into consideration the effects of video compression on the PRNU noise in video frames, but rather consider video frames as isolated images of equal importance.
