I am trying to segment a 3D shape using levelset. I want to track shape movement in consecutive frames.
Now I want to create a
signed distance function matrix for initialization of levelset algorithm using previous frame surface calculated as 3D points.
First, I have to create a logical 3D matrix in which all points inside previous frame surface points are '1' and '0' otherwise. Then I have to calculate
3D signed distance function matrix from it.
How can I do that?
Thank you for your help.
