Morphing Techniques

  • Atlas: turn .obj model into image of surface points
  • Morph atlas into segmented model

Thin-Plate Spline Transform

  • MATITK
  • Quick computer computation, but user has to manually choose corresponding points
  • Allows <1200 user defined registration points
  • Input: Atlas and before/after corresponding points (a, b, c, ...)
  • output = matitk('rtps',[],input,input,[x1(a) y1(a) z1(a) x2(a) y2(a) z2(a) x2(b)...]

B-Spline Transform

  • ITK
  • Entirely automated
  • >12 hours
  • No need to select corresponding points
  • Input: Atlas and LW output
