[Insight-users] problem about the definition of the curvature speed term in level set

[diaoxianfen]

Hello,
    I want to know how the curvature speed term is defined in the level set algorithm. Gaussian or mean curvature?
    When use the level set algorithm in SNAP to segment the medical image, the input image is mapped to the feature image with values between [0,1] or [-1,+1].The feature image is used to define the propagation speed term.I think the curvature speed term should be computed at each pixel. Is it computed using the feature image? Does the isoContour with the value at the pixel need be created to compute the curvature?
    Any information about this will be appreciated.
