Hi All,
The CurvatureFlow filter requires two parameters, the number of iterations to be performed and
the time step used in the computation of the level set evolution and are set by
the methods SetNumberOfIterations() and SetTimeStep() respectively.
The level set function is evolved under the control of a diffusion equation where the speed is proportional to the curvature of the contour:
I(t) = K. delta(I)
question is-->
What is "K" and how it's value is decided? While using Curvature Flow Filter, we don't set this paramter while it plays important role in calculating the level set.
Any input on this appreciated.
Thanks,
Neha
