Evaluation of medical image watermarking with Tamper Detection and Recovery (AW-TDR)

This paper will study and evaluate watermarking technique by Zain and Fauzi [1]. Recommendations will then be made to enhance the technique especially in the aspect of recovery or reconstruction rate for medical images.
