Abstract
Combining non-local means (NLM) filter with appropriate fuzzy cluster criterion, objective and subjective manners with synthetic brain Magnetic Resonance Imaging(MRI) are evaluated. Experimental results show that noise is effectively suppressed while image details are well kept, compared with the traditional NLM method. Meanwhile, quantitative and qualitative results indicate that artifacts are greatly reduced in our proposed method and brain MR images are typically enhanced.
