NOVEL SIMILARITY INVARIANT FOR SPACE CURVES USING TURNING ANGLES AND ITS APPLICATION TO OBJECT RECOGNITION
2009 IEEE INTERNATIONAL CONFERENCE ON ACOUSTICS, SPEECH, AND SIGNAL PROCESSING, VOLS 1- 8, PROCEEDINGS, pp. 1277–1280.
author keywords: Space curve; similarity invariant; turning angle; curvature; torsion
TL;DR:
This paper presents a new similarity invariant signature for space curves based on the information contained in the turning angles of both the tangent and the binormal vectors at each point on the curve, and defines a Riemannian metric on the space of the invariant.

Squigraphs for Fine and Compact Modeling of 3-D Shapes
IEEE TRANSACTIONS ON IMAGE PROCESSING, 19(2), 306–321.
author keywords: Iso-geodesic curves; object matching; Reeb graph; shape geometry; topo-geometric modeling; Whitney embedding
TL;DR:
The experiments show that squigraphs are more general than existing techniques and achieve similar classification rates to those achieved by classical shape descriptors, however, their performance becomes clearly superior when finer classification and identification operations are targeted.

Geometric modeling of rigid and non-rigid 3D shapes using the global geodesic function
Pattern Recognition, 935–942.
TL;DR:
The experimental results show that the proposed modeling of objects to their topological graphs to ensure a full and compact description necessary for shape-based retrieval, recognition and analysis of 3D models appears to be robust to both noise and decimation.
