Statistical shape models have become a widely used tool in computer vision and medical image analysis where they are of considerable interest when studying shape variations in anatomical shapes. The objective of this article is to build a 3D statistical shape modeling for a given data; the implemented process goes through those basic steps, first ...

Registration is the problem of bringing together two or more 3D shapes, either of the same object or of two different but similar objects. This chapter first introduces the classical Iterative Closest Point (ICP) algorithm, which represents the gold standard registration method. Current limitations of ICP are addressed and the most popular variants are

3D cameras are matrix sensors that estimate depth and capture range maps. Similar to color cameras, they provide images of the surrounding environment as seen from a single point of view. Alongside the color information, Three-dimension (3D) cameras provides depth measurements by exploiting visual information.

A new account of how we perceive the 3D shapes of objects and how to design machines that can see shapes the way we do. The uniqueness of shape as a perceptual property lies in the fact that it is both complex and structured. Shapes are perceived veridically—perceived as they really are in the physical world, regardless of the ...

Shaping 3D multimedia environments
Proceedings of the 6th ACM international conference on Image and video retrieval, 2007In this paper we describe The MediaSquare, a 3D Multimedia Environment we are currently developing, where users are impersonated as avatars enabling them to browse and experience multimedia content by literally walking through it. Users may engage in conversations with others, exchange experiences as well as collaboratively explore and enjoy the ...

3D Isometric shape correspondence
2010 IEEE 18th Signal Processing and Communications Applications Conference, 2010We address the problem of correspondence between 3D isometric shapes. We present an automatic method that finds the optimal correspondence between two given (nearly) isometric shapes by minimizing the amount of deviation from isometry. We optimize the isometry error in two steps.

Differential 3D shape retrieval
Optics and Lasers in Engineering, 2014Abstract We are presenting a differential three-dimensional (3-D) shape profiling method that is based on the combination of orthogonal fringe projection. It allows us to compute depth gradient maps in a fast and efficient manner. What we are demonstrating is that depth gradients can be computed in a simple way by measuring fringe deformation ...

Indirect shape analysis for 3D shape retrieval
Computers & Graphics, 2015We introduce indirect shape analysis, or ISA, where a given shape is analyzed not based on geometric or topological features computed directly from the shape itself, but by studying how external agents interact with the shape. The potential benefits of ISA are two-fold.

Hallucinating 3D facial shapes
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008This paper focuses on hallucinating a facial shape from a low-resolution 3D facial shape. Firstly, we give a constrained conformal embedding of 3D shape in R2, which establishes an isomorphic mapping between curved facial surface and 2D planar domain.

This chapter describes three different techniques for vision-based reconstruction of 3D shapes. The use of structured lighting is a relatively simple but accurate method. Stereo vision might be called the 3D shape-reconstruction method in computer vision; its actual stereo-matching challenges are a subject in the following chapter; here we only discuss
