Analysis of blind image watermarking algorithms

Abstract

This paper presents an overview of blind image watermarking algorithms. In this paper, we analyzed these algorithms for different criteria like robustness, security, and imperceptibility. We also compared pros and cons of using blind method for embedding and extraction of watermark. Most of these algorithms are implemented using MATLAB 2011 and tested on the standard image dataset. We used true color images of size 256 × 256 and binary watermarks of size 32 × 32 for testing. This paper will help watermarking researcher to choose the particular algorithms depending on their need for the application they are working on.
