Thin Plate Spline (TPS) Analysis

• TPS comparison of two shapes
  • Comparison of male vs female wing shape in Drosophila
• TPS warp analysis
  • Principal Warp display with Mage
    • Gypsy moth populations
    • Drosophila melanogaster sexual dimorphism of wings
    • Noctuid moth species differences in wing landmarks
• TPS regression
  • TPS factorial regression of Drosophila wing shape on sex and strain
  • The TPS sexual component of the above regression analysis showing a clear dilation of the distal wing blade in the male vs female.
• TPS superimposition
  • Alignment and averaging of Drosophila melanogaster wings.
  • Alignment and averaging of two human images: Edgar and Joe
  • Alignment and averaging of Catocala ultronia morphs:
• TPS tree analysis
• TPS small difference criterion
