Prolonged recovery of 3D printed, photo-cured polylactide shape memory polymer networks
APL Bioengineering, 2020 Shape memory polymers are materials that are able to retain a deformed state until an external stimulus, most typically heat, triggers recovery to the original geometry.

Automatic 3D shape recovery for rapid prototyping
Virtual and Physical Prototyping, 2008 The capacity to create, display and manipulate a three-dimensional (3D) computer model and produce a physical replica of an existing object, enabling 3D re-shaping activities, plays an important role in different areas such as engineering, biology, architecture and archaeology.

3D Textured Shape Recovery with Learned Geometric Priors
, 2022 3D textured shape recovery from partial scans is crucial for many real-world applications. Existing approaches have demonstrated the efficacy of implicit function representation, but they suffer from partial inputs with severe occlusions and varying object types, which greatly hinders their application value in the real world.

3D shape recovery using a deformable model [PDF]
Image and Vision Computing, 1994 Abstract This paper describes a method for recovering the 3D shape of a moving object from a sequence of images. While following the motion of the object a 3D surface model, initialized to be spherical, progressively deforms under the action of simulated external forces driving its profile towards the object profile extracted from the image. Internal

Local deformation models for monocular 3D shape recovery [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 Without a deformation model, monocular 3D shape recovery of deformable surfaces is severely under-constrained. Even when the image information is rich enough, prior knowledge of the feasible deformations is required to overcome the ambiguities. This is further accentuated when such information is poor, which is a key issue that has not yet been ...

A model-based approach to recovering the structure of a plant from images [PDF]
, 2015 We present a method for recovering the structure of a plant directly from a small set of widely-spaced images. Structure recovery is more complex than shape estimation, but the resulting structure estimate is more closely related to phenotype than is a ...

Annals of "Dunarea de Jos" University of Galati, Fascicle XII, Welding Equipment and Technology, 2020 The 4D additive manufacturing processes are considered today as the "next big thing" in R&D. The aim of this research is to provide two examples of commercial PLA based shape memory polymer (SMP) objects printed on an open-source 3D printer in order to ...

3D shape based reconstruction of experimental data in Diffuse Optical Tomography [PDF]
, 2009 Diffuse optical tomography (DOT) aims at recovering three-dimensional images of absorption and scattering parameters inside diffusive body based on small number of transmission measurements at the boundary of the body.

End-to-end Recovery of Human Shape and Pose
, 2018 We describe Human Mesh Recovery (HMR), an end-to-end framework for reconstructing a full 3D mesh of a human body from a single RGB image. In contrast to most current methods that compute 2D or 3D joint locations, we produce a richer and more useful mesh ...
