Implementation of a spatial domain salient region based digital image watermarking scheme

Abstract

Digital domain is today's most preferred area for data processing and transmission. In case of data augmentation or authorized replication, copyright protection has become an exigent challenge. Digital watermarking is a conventional procedure to serve this purpose. Here a spatial domain image watermarking scheme is developed through a pixel based saliency map where the inadequate nature of human visual system is utilized. The experimental results and a brief assessment with some existing frameworks confirm that this proposed scheme not only makes the information transparent into the cover object but also provides superior robustness and hiding capacity.
