Denoise a binary image using min/max curvature flow.
BinaryMinMaxCurvatureFlowImageFilter implements a curvature driven image denosing algorithm. This filter assumes that the image is essentially binary: consisting of two classes. Iso-brightness contours in the 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 a user specified value which discriminates between the two pixel classes.
This filter make use of the multi-threaded finite difference solver hierarchy. Updates are computed using a BinaryMinMaxCurvatureFlowFunction object. A zero flux Neumann boundary condition is used when computing derivatives near the data boundary.
