The visual perception of 3D shape
Trends in Cognitive Sciences, 2004A fundamental problem for the visual perception of 3D shape is that patterns of optical stimulation are inherently ambiguous. Recent mathematical analyses have shown, however, that these ambiguities can be highly constrained, so that many aspects of 3D structure are uniquely specified even though others might be underdetermined.

Proceedings of the 1st international conference on Computer graphics and interactive techniques in Austalasia and South East Asia - GRAPHITE '03, 2003
The research of 3D shape matching starts to get more attention recently. In this short paper, we present a 3D shape matching framework. First, we give a general definition of similarity value of two objects. Then, an algorithm is proposed consisting of Principal Component Analysis (PCA), voxelization, and iterative coarse-to-fine aligning of two ...

Learning Barycentric Representations of 3D Shapes for Sketch-Based 3D Shape Retrieval
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017Retrieving 3D shapes with sketches is a challenging problem since 2D sketches and 3D shapes are from two heterogeneous domains, which results in large discrepancy between them. In this paper, we propose to learn barycenters of 2D projections of 3D shapes for sketch-based 3D shape retrieval.

On the Multiscale Representation of 2D and 3D Shapes
Graphical Models and Image Processing, 1999Summary: Binary pyramids in two and three dimensions can be used for multiresolution representation. The ``standard'' OR and AND pyramids have serious drawbacks, as they distort the shape significantly; therefore they can seldom be used effectively.

2012 12th International Conference on Control Automation Robotics & Vision (ICARCV), 2012
The talk will begin with an overview of the state-of-the-art in the 3R's of computer vision: registration, reconstruction and recognition and will include demonstrations of research which has been recently commercialised at Cambrdige (Zappar, Metail, Toshiba gesture interfaces and Microsoft Kinect).

This paper reviews main approaches to 3D shape perception in both human and computer vision. The approaches are evaluated with respect to their plausibility of generating adequate explanations of human vision. The criterion for plausibility is provided by existing psychophysical results. A new theory of 3D shape perception is then outlined.
