Min/Max Curvature Flow

Class: NodeImageMinMaxCurvatureFlowFilter

Node Icon

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.

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, the stencil radius, governs the scale of the noise to be removed.
