Abstract :
We propose a robust video hash function for broadcast monitoring and database search applications. The method consists of binarized low-frequency components of the 3D-DCT transform of video sequences. Simulation experiments show that the perceptual hash function is unique for different video content, but that it remains invariant under selected signal processing attacks.
