Model-based 2D-Shape Recovery

1995
The paper presents a new approach for the reconstruction of polygons using local and global constraints. The MDL-based solution is shown to be useful for analysing range and image data of buildings.

Shape Recovery and Mechanical Properties of Shape Memory Composites

Volume 1: Advances in Aerospace Technology, 2008
As the need for deployable space structures continues to increase, a deeper understanding of the mechanical properties and the responses of shape memory composites will be needed. Past research efforts have been focused on woven (0/90) carbon fiber composites which limit the shape memory capabilities due to the brittle nature of this fiber. The current

Shape from recognition: a novel approach for 3-D face shape recovery

IEEE Transactions on Image Processing, 2001
In this paper, we develop a novel framework for robust recovery of three-dimensional (3-D) surfaces of faces from single images. The underlying principle is shape from recognition, i.e., the idea that pre-recognizing face parts can constrain the space of possible solutions to the image irradiance equation, thus allowing robust recovery of the 3-D ...

Self‐Healing Polyurethanes with Shape Recovery

Advanced Functional Materials, 2014
Two new thermoresponsive self‐healing polyurethanes (1DA1T and 1.5DA1T) based on the Diels–Alder (DA) reaction between furan and maleimide moieties are developed that use the shape‐memory effect to bring crack faces into intimate contact such that healing can take place.

Shape recovery using dynamic subdivision surfaces

Sixth International Conference on Computer Vision (IEEE Cat. No.98CH36271), 2002
A new dynamic subdivision surface model is proposed for shape recovery from 3D data sets. The model inherits the attractive properties of the Catmull-Clark subdivision scheme and is set in a physics-based modeling paradigm. Unlike other existing methods, our model does not require a parameterized input mesh to recover shapes of arbitrary topology ...

Shape recovery from equal thickness contours

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2000
A unique imaging modality based on equal thickness contours (ETC) has introduced a new opportunity for 3D shape reconstruction from multiple views. These ETC can be generated through an interference between transmitted and diffracted beams. We present a computational framework for representing each view of an object in terms of its object thickness and

Shape memory polymers with controlled time-dependent shape recovery

2013
The aim of this thesis has been to investigate the use of heat-activated shape memory polymers (SMPs) as novel smart actuators for the controlled delivery of fluids and their suitability for applications such as low-cost drug delivery. On heating to temperatures in the vicinity of their glass transition temperature, Tg, amorphous SMPs are able to ...

Silhouette-Based 3D Face Shape Recovery

2003
Though realistic eulerian fluid simulation systems now provide believable movements, straightforward renderable surface representation, and affordable computation costs, they are still unable to deal with non-static objects in a realistic manner. Namely, objects can not have an influence on the fluid and be simultaneously affected by the fluid's motion.

Shape memory hydrogels with remodelable permanent shapes and programmable cold-induced shape recovery behavior

Soft Matter
A self-healing hydrogel that can be stiffened with heat was designed. The synergy of self-healing and thermal hardening properties generated several interesting functions, such as programmable shape memory, impact protection and recyclability.

How Do Credit Conditions Shape Economic Recoveries

2011
This paper investigates the role of credit in shaping economic recoveries and tries to shed some light on the phenomenon of creditless recoveries using industry-level data for a large sample of countries. We find that while a failure of the credit stock to recover to its pre-crisis level does not hamper growth, a failure of credit flows to recover ...
