    Asm(Uppsala) Asm(Uppsala) Presentation Transcript

    • A.Rahim Kadkhodamohammadi January, 2011
      • Point Distribution Model
      • Training: Apply PCA to labeled images
      • New image
        • Project mean shape
        • Iteratively modify model points to fit local neighborhood
      • Landmark points
      • Interpolation
      • Align all shape
      • PCA
    •  
      • Looking for Landmarks
      • Gray Level Profile (GLP)
      • Shape deformation:
        • Scaling
        • Translation
        • rotation
        • Allowable displacement
    •

    •  
      • Multi-resolution (Scale Space)
      • Line Search
      • Initialization
      • Variation of Principal Component
      • ASM is relatively fast
      • ASM too simplistic; not robust when new images are introduced
      • May not converge to good solution
      • Questions and Comments are Welcome
      Thank You
