| Outline of Final Research Achievements |
A non-local means (NLM) filter has been proposed, which can effectively remove noise with preserving edge in return for computational burden. We have therefore developed an accelerating software of the 3D NLM filter by general-purpose graphics processing units (GPGPU), which enables massively parallel computing. In the study, we applied the software to human and animal brain MRI and demonstrated that it is useful not only for basic but also clinical researches.
