MRI Denoising Methods
Filtering Approach
Spatial Filtering, Temporal filtering, Averaging and Sampling
-
NLM filter
•Weight of the pixels is required to calculate, so this method suffers from computational complexity.
Bilateral filter
•Neighbor pixels are used to define the center pixel value. Generally a narrow spatial window is used for this purpose, so there may be chance to recognize small structure as noise.
