We propose a sketch-based 3D shape retrieval system that is substantially more discriminative and robust than existing systems, especially for complex models. The power of our system comes from a combination of a contourbased 2D shape representation and a robust sampling-based shape matching scheme. They are defined over discriminative local features and applicable for partial sketches; robust ...

Retrieval image by shape similarity, given a template shape is particularly challenging, owning to the difficulty to derive a similarity measurement that closely conforms to the common perception of similarity by humans. In this paper, a new method for the representation and comparison of shapes is present which is based on the shape matrix and snake model. It is scaling, rotation, translation ...

There are numerous applications where geometric patterns need to be checked and compared. An important class of applications are industrial inspection systems and retrieval systems, which search an object from a large database. Morphology based shape representation approach is one of the simplest structural representation methods which represents the shape by simpler shape components. In this p...

A bstract To explore the interplay of NLO matching and next-to-leading logarithmic (NLL) parton showers, we consider simplest case γ * Higgs-boson decays to $$ q\overline{q} q ¯ gg respectively. Not only should shower NLL accuracy be retained across observables after ...
