    Regularization of Shape

    L-shape smoothing:

    Sequences of splices smoothes

    boundary, while preserving the

    corner.

    by Huseyin Tek

    Edge grouping & Gap filling:

    Rectangle with gaps being filled in:

    removing a skeleton branch involves

    a shape transform, here a gap completion.

    by Huseyin Tek

    Spurious elements removal:

    Spurious elements create additional

    graph structures, here loops, which can

    be removed to recover a cleaner shape.

    Shape Transforms via Symmetry Maps

    Dot grouping:

    Dots patterns are grouped

    hierarchically and a smooth

    boundary trace recovered.

    Occlusion Transform:

    Occluded rectangle is

    recovered, as well as the

    occluding elements.
