Optimum decoder for multiplicative spread spectrum image watermarking with Laplacian modeling
Volume 8, Issue 2 , July 2016, , Pages 131-139
Abstract
This paper investigates the multiplicative spread spectrum watermarking method for the image. The information bit is spreaded into middle-frequency Discrete Cosine Transform (DCT) coefficients of each block of an image using a generated pseudo-random sequence. Unlike the conventional signal modeling, ... Read MoreRobust multiplicative video watermarking using statistical modeling
