一种用于帧内篡改检测的压缩感知视频水印实现算法
A Video Watermarking Algorithm for Intraframe Tampering Detection Based Compressed Sensing
摘要
Abstract
In order to overcome the drawback of localization accuracy for intraframe tampering detection based on video wa-termarking ,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 ,U and V ,feature pa-rameters of I-VOP(Intra-Video Object Plane) frame ,are extracted utilizing projection of DCT (Discrete Cosine Transform) mea-surement matrix of the CS ,generate the CS-watermarking of the video content ,and embed the CS-watermarking data into the coeffi-cients of low frequency and high frequency of DCT domain in the Y component of image .Compared to Hash-watermarking generat-ing algorithm ,experiment results show that the CS-watermarking algorithm has better data recovery capability and localization accu-racy for video intraframe tampering detection .关键词
