  Abstract


A novel edge preserving nonlocal means (NLM) technique pertaining to MR images perturbed with Rician noise is presented in this paper. Earlier proposed techniques over-smoothes the MR image and hence edge preservation was difficult.Also nonlocal means filter when carried-out on 3D images, slows down the denoising process. In our work we have optimized the denoising algorithm to achieve higher speed and better accuracy using principal component analysis technique. We have tested our proposed method on simulated, clinical and pathological image sets. With a wide variety of evaluation metrics such as PSNR, BC, UQI and visual inspection itis found that the proposed technique outperforms other techniques qualitatively and quantitatively. The proposed method is 6.8 times faster than all other methods in comparison.
