Abstract PolyDiMethylSiloxane (PDMS) is an elastomer increasingly used to produce soft objects by replication, in a variety of fields including electronics, microfluidics, tribology, biomechanics and robotics. While PDMS replication usually considered faithful at all scales, down nanoscales, detailed quantitative comparisons between the geometric features mold replicated object are still requir...

This paper presents a novel approach to surface representation based on its di erential deformations, and is an extension to surfaces of the \shape from deformation" framework for curves [31]. A representation of 3D shape for recognition must capture the multidimensional nature of shape, as well as the notion of a hierarchy of scale. A range of deformations can capture both: while constant defo...
