#include <itkMinMaxCurvatureFlowImageFilter.h>
Denoise an image using min/max curvature flow.
MinMaxCurvatureFlowImageFilter implements a curvature driven image denoising algorithm. Iso-brightness contours in the grayscale input image are viewed as a level set. The level set is then evolved using a curvature-based speed function:
where if is less than or equal to and , otherwise. is the mean curvature of the iso-brightness contour at point .
In min/max curvature flow, movement is turned on or off depending on the scale of the noise one wants to remove. Switching depends on the average image value of a region of radius around each point. The choice of , the stencil radius, governs the scale of the noise to be removed.
The threshold value is the average intensity obtained in the direction perpendicular to the gradient at point at the extrema of the local neighborhood.
This filter make use of the multi-threaded finite difference solver hierarchy. Updates are computed using a MinMaxCurvatureFlowFunction object. A zero flux Neumann boundary condition is used when computing derivatives near the data boundary.
