Wave atom-SVD based digital image watermarking scheme

Digital watermarking is a technique of embedding some information (usually hidden copyright notices) into an image. It has found applications in a number of varied fields like copyright protection, content authentication, document annotation, medical imaging. In this paper we propose a hybrid image watermarking technique based on wave atom transform and singular value decomposition (SVD). Experimental results clearly show that this proposed scheme is quite resilient to various image processing attacks.
