Perceptual Organization:The organization of local image image fragments into the global structure
Outline 1. ScaleSpace Repr. 2. Orientation Score
Part 1. Scale Space The notion of scale :
Scale Space Theory Axioms Gaussian scale space ? - NO ! Axioms
Scale Space Theory Generator: Gaussian SS: Poisson SS:
Deep Structure: Top-points:
Top-point Reconstruction Gelfand Triples Sobolev/Traj. Spaces Reproducing Kernels
If energy is norm on Hilbert space exact solution is obtained by orthogonal projection :
Fast Top-point Reconstruction on large images,cooperation with Frans Kanters, Bart Janssen : Cooperation with Frans Kanters, Bart Janssen
Stability Transformations : Reducible Generalization wavelet theory :
Processing on Orientation Scores image score processed image processed score Euclidean-invariant iff Left-invariant
Application Automatic Closure of Gaps: Collision probability of forward and backward proces:
Orientation scores of 3D images (Euler angles) image orientation score
