Patient information is embedded inside the medical images for the storage or transmission, or healthcare applications.In medical image processing, various types of noises corrupt the image quality.There is a need of measure specific noise for a particular image is required for the evaluation of robustness for embedding techniques used for hiding patient information in medical images.It is very important to obtain precise images to facilitate accurate analysis and estimation of noise in embedded medical image.The current work is focused towards studying the effect of specific noise which affect particular medical image.The strength of the medical image is tested by introducing several attacks to the embedded medical images.The statistical quantity measures like peak signal-to-noise ratio (PSNR), signal-to-noise ratio (SNR) and normalized root mean square error (NRMSE) are employed to measure the quality of the output medical image.
