Abstract

This paper presents a high capacity watermarking technique in the spatial domain for gray-scale brain MRI. A new scheme, based on Fibonacci decomposition and Knight’s Tour algorithm is proposed in order to increase the hiding capacity for brain MRI. The effectiveness of the proposed scheme is proven by conducting series of experiments with image quality measure matrices namely PSNR and SSIM to allow us to state that the proposed scheme is capable of providing confidentiality to medical images. The experimental results also demonstrate that the proposed scheme has higher capacity compared to other watermarking techniques
