Analysis of Robustness and Invisibility on a Medical Image Watermarking Algorithm

Preeti Sharma.

Abstract
The present paper extends another different diffusing spectrum hinged technique of image-adaptive
watermarking. Here discriminative implantation ofwatermark issettled in compactfabricated slabs of the image,
contingent alongside the individual entropyof the slabs. The unfamiliarity of this practice lies down in the
pliability of its power factor that can be altered comfortably in the interest to procureaintegral level of optical
grade of the watermarkedimage. This variable strength factor (VSF) is calculated using standard deviation of
Discrete Wavelet Transform (DWT) measure of blocks with elevated entropy. The robustness of this technique
is verified by studying the relationship between the imperceptibilityof the watermarked image and recovery of
the watermark for different values of VSF. The invisibility of the received watermarked image is determined
utilizing Peak Signal to Noise Ratio (PSNR) and recovery of the watermark is calculated as Bit Error Rate
(BER). The technique may be used for safeguarding the ownership of medical images

Key words: image-adaptive watermarking, PSNR, BER, variable strength factor, telemedicine
