Abstract

In order to overcome the drawback of localization accuracy for intraframe tampering detection based on video watermarking

this paper proposes a novel video watermarking generation and intraframe tampering detection algorithm based on feature representation of MPEG-4(Moving Picture Experts Group-4) video content by compressed sensing(CS).First

and

feature parameters of I-VOP(Intra-Video Object Plane) frame

are extracted utilizing projection of DCT(Discrete Cosine Transform) measurement matrix of the CS

generate the CS-watermarking of the video content

and embed the CS-watermarking data into the coefficients of low frequency and high frequency of DCT domain i

n the

component of image.Compared to Hash-watermarking generating algorithm

experiment results show that the CS-watermarking algorithm has better data recovery capability and localization accuracy for video intraframe tampering detection.
