The method is based on Time-Domain constrained (TDC) estimator in which the residual noise energy is kept below a threshold while minimizing the signal distortion. The denoising technique employed prewhitening method prior to the subspace filter which is proven to give remarkable results. Experiments were carried out on noise-free images corrupted with simulated additive white noise. The results indicated that the proposed methods provide performance better than the compared methods in terms of the correlation coefficient and SSIM index. © 2011 IEEE. date: 2011 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84857067784&doi=10.1109%2fNatPC.2011.6136443&partnerID=40&md5=19eaf2b42c15480235c0b567001ecab1 id_number: 10.1109/NatPC.2011.6136443 full_text_status: none publication: 2011 National Postgraduate Conference - Energy and Sustainability: Exploring the Innovative Minds, NPC 2011 place_of_pub: Perak refereed: TRUE isbn: 9781457718847 citation: Yahya, N. and Kamel, N.S. and Malik, A.S.
