What Shape Are Dolphins? Building 3D Morphable Models from 2D Images

Thomas J. Cashman, Andrew W. Fitzgibbon
2013 IEEE Transactions on Pattern Analysis and Machine Intelligence  
3D morphable models are low-dimensional parametrizations of 3D object classes which provide a powerful means of associating 3D geometry to 2D images.  ...  Index Terms-Morphable model, shape from silhouette, subdivision surfaces, image-based modelling, single-view reconstruction. ! • T. Cashman is with the Faculty  ...  We thank the following copyright holders for permission to reproduce their photographs in this paper: Tim Nicholson for all dolphins except leftmost and rightmost images in Figure 1 ; Peter Asprey 1 for  ...

Balloon Shapes: Reconstructing and Deforming Objects with Volume from Images

Sara Vicente, Lourdes Agapito
2013 2013 International Conference on 3D Vision  
Reconstructing the shape of a deformable object from a single image is a challenging problem, even when a 3D template shape is available.  ...  In contrast, we are interested in recovering the full shape of a deformable 3D object. We introduce a new method designed to reconstruct closed surfaces.  ...  models from 2D images [7] .  ...

Lifting Object Detection Datasets into 3D [article]

Joao Carreira, Sara Vicente, Lourdes Agapito, Jorge Batista
2016 arXiv   pre-print
In particular, acquiring ground truth 3D shapes of objects pictured in 2D images remains a challenging feat and this has hampered progress in recognition-based object reconstruction from a single image  ...  We hope that our results will re-stimulate interest on joint object recognition and 3D reconstruction from a single image.  ...  Reconstruction using morphable models When multiple 3D shapes corresponding to different instances of the same class are available, they can be used to build a morphable model for the 3D class, that can  ...

C3DPO: Canonical 3D Pose Networks for Non-Rigid Structure From Motion [article]

David Novotny, Nikhila Ravi, Benjamin Graham, Natalia Neverova, Andrea Vedaldi
2019 arXiv   pre-print
We propose C3DPO, a method for extracting 3D models of deformable objects from 2D keypoint annotations in unconstrained images.  ...  We do so by learning a deep network that reconstructs a 3D object from a single view at a time, accounting for partial occlusions, and explicitly factoring the effects of viewpoint changes and object deformations  ...  What [22] Suryansh Kumar, Anoop Cherian, Yuchao Dai, and shape are dolphins? building 3d morphable models Hongdong Li.  ...

Development and validation methodology of the Nuss procedure surgical planner

Krzysztof J Rechowicz, Frederic D McKenzie
2013 Simulation (San Diego, Calif.)  
First, a generic model of the ribcage is developed to overcome the issue of missing cartilage when PE ribcages are segmented and facilitate the flexibility of the model to accommodate a range of deformity  ...  Then, the CT data collected from actual patients with PE is used to create a set of patient specific finite element models.  ...  Once the morphable or average model has been developed, the 3D shape and texture of a new face can be reconstructed from a single image provided.  ...

Technology-Facilitated Diagnosis and Treatment of Individuals with Autism Spectrum Disorder: An Engineering Perspective

Xiongyi Liu, Qing Wu, Wenbing Zhao, Xiong Luo
2017 Applied Sciences  
Based on this model, we organize our review with the following questions: (1) What are presented to the participants in the studies and how are the content and delivery methods enabled by technologies?  ...  (2) How are the reactions/inputs collected from the participants in response to the stimuli in the studies?  ...  In the first step, AAMs are used to build a set of models based on the appearance and shape of the person's face. The learned models are used to produce an AAM mesh.  ...

Data-driven approaches for interactive appearance editing [article]

Hoang Chuong Nguyen, Universität Des Saarlandes, Universität Des Saarlandes
2015
Next, the thesis proposes shape and color subspaces of an object that are learned from a collection of exemplar images.  ...  Along this line, an example-based material assignment approach is proposed, where the 3D models of a virtual scene can be "materialized" simply by giving a guidance source (image/video).  ...  Other instances of appearance editing are shape manipulation in 2D images or geometry modeling in 3D.  ...
