Abstract : In this work, we propose a method of embedding patient data with a medical image using a perceptual quality measure (PQM). The PQM will evaluate the visible distortions between the original image and the processed image. The proposed PQM is based on the error in the Contrast energy which has been estimated using a contrast sensitive function (CSF). A perceptual quality distortion measure (PQDM) has been defined to measure the perceptual difference due to data embedding into the image.
