Our former resident artist in ISR, Rudolfo Quintas, explored how to use vision controlled instruments…with fire!

BMVC2009: Non-rigid structure from motion using quadratic deformation models.This approach uses a novel quadratic deformation model which is able to represent non-linear non-rigid motions such as bending, stretching, shearing and twisting. More details can be found in our BMVC paper. |

New (CVPR2009): Factorization for Non-Rigid and Articulated Structure using Metric Projections. We propose a new algorithm for recovering the 3D shape and motion of deformable and articulated objects purely from uncalibrated 2D image measurements. Such problem is solved with an alternate least-squares approach associated with a globally optimal projection step onto the manifold of metric constraints. An important advantage of this new algorithm is its ability to handle missing data. |

Recovering Euclidean Deformable Models from Stereo-motion
|
ICPR2008: A stereo-motion approach able to infer 3D nonrigid models from uncalibrated stereo images. The stereo setup dramatically improves the 3D model estimation when the observed 3D shape is mostly deforming without undergoing strong rigid motion. In collaboration with Xavier Llado and Lourdes Agapito. |
A model of brightness variations due to illumination changes and non-rigid
motion using spherical harmonics
 |
BMVC2008: Pixel brightness variations in an image sequence depend both on the objects surface reflectance and on the motion of the camera and object. In such context, we propose a new model able to describe image variations in terms of deformation and luminance changes. This model describes brightness variations with two independent components represented as linear basis shapes. Lighting influence is represented in terms of Spherical Harmonics and non-rigid motion as a linear model which represents image coordinates displacement. In collaboration with PCR. |
A Factorization Approach to Structure from Motion with Shape Priors
 |
CVPR2008: An approach for including 3D prior models into a factorization framework for structure from motion. The proposed method computes a closed-form affine fit which mixes the information from the data and the 3D prior on the shape structure. Here you can find a description of the approach. |
