Application of MATLAB in Digital Image Watermarking
Liu Shu-qing · Journal of Southern Vocational Education · 2011
Digital watermarking technology is the image,text,numbers,signs and other copyright information embedded into multimedia data,an effective way to protect digital copy right.MATLAB language has a powerful matrix operations and image processing capabilities and is a highly efficient engineering computing language.This paper presents a simulation using the MATLAB language about discrete wavelet transform watermarking algorithm as an instance.From the example we can see that the use of MATLAB algorithms quickly implements the simulation and greatly improves the experimental efficiency.
