GeoTopo: Dynamic 3D Facial Expression Retrieval Using Topological and Geometric Information
(The Eurographics Association, 2014)
Recently, a lot of research has been dedicated to address the problem of facial expression recognition in dynamic sequences of 3D face scans. On the contrary, no research has been conducted on facial expression retrieval ...
Symmetry and Fourier Descriptor: A Hybrid Feature For NURBS based B-Rep Models Retrieval
(The Eurographics Association, 2014)
As the number of models in 3D databases grows, an efficient 3D models indexing mechanism and a similarity measure to ease model retrieval are necessary. In this paper, we present a query-by-model framework for NURBS based ...
