A comparison of isotropic Gaussian smoothing with vasculature smoothing. The independent components from vasculature smoothing are less noisy and more structured.

Vasculature-informed spatial smoothing of white matter functional magnetic resonance imaging. SPIE Medical Imaging: Image Processing, 2025, February, San Diego, California. https://doi.org/10.1117/12.3047240. Abstract Blood oxygenation level-dependent (BOLD) signals in white matter in the brain are anisotropically oriented, so...

Two image filters. One says isotropic Gaussian smoothing. The second says diffusion-informed spatial smoothing and shows a spatially varying filter.
