Accurate Reconstruction of Oriented 3D Points using Affine Correspondences

no code implementations ECCV 2020 Carolina Raposo, Joao P. Barreto

Affine correspondences (ACs) have been an active topic of research, namely for the recovery of surface normals.

Video-based computer aided arthroscopy for patient specific reconstruction of the Anterior Cruciate Ligament

no code implementations25 Jul 2018 Carolina Raposo, Cristovao Sousa, Luis Ribeiro, Rui Melo, Joao P. Barreto, Joao Oliveira, Pedro Marques, Fernando Fonseca

The Anterior Cruciate Ligament (ACL) tear is a common medical condition that is treated using arthroscopy by pulling a tissue graft through a tunnel opened with a drill.

3D Registration of Curves and Surfaces using Local Differential Information

no code implementations CVPR 2018 Carolina Raposo, Joao P. Barreto

Comparative experiments demonstrate that the proposed algorithm is the first effective solution for curve vs surface registration, with the method achieving accurate alignment in situations of small overlap and large percentage of outliers in a fraction of a second.

Theory and Practice of Structure-From-Motion Using Affine Correspondences

no code implementations CVPR 2016 Carolina Raposo, Joao P. Barreto

Affine Correspondences (ACs) are more informative than Point Correspondences (PCs) that are used as input in mainstream algorithms for Structure-from-Motion (SfM).

Single-Image Estimation of the Camera Response Function in Near-Lighting

no code implementations CVPR 2015 Pedro Rodrigues, Joao P. Barreto

The camera response function (CRF) relates quantised image pixel values with physical incoming light.

A Global Approach for the Detection of Vanishing Points and Mutually Orthogonal Vanishing Directions

no code implementations CVPR 2013 Michel Antunes, Joao P. Barreto

This article presents a new global approach for detecting vanishing points and groups of mutually orthogonal vanishing directions using lines detected in images of man-made environments.
