3D Object Recognition by Eigen-Scale-Space of Contours
People often recognize 3D objects by their boundary shape. Designing an algorithm for such a task is interesting and useful for retrieving objects from a shape database. In this pa...

Overcomplete image coding using iterative projection-based noise shaping
Overcomplete transforms, like the Dual-Tree Complex Wavelet Transform, offer more flexible signal representations than criticallysampled transforms. Large numbers of transform coe...

Transitions of the Pre-Symmetry Set
The Symmetry Set (??) and its subset the Medial Axis (? ), can be used to describe a shape. The representation of the ?? in parameter space is called the pre-Symmetry Set. Changes...
