Research Interests

My research interests lie in the area of Computer Vision, more specifically in the 3D reconstruction problem from a multi-camera setup. A key step to reconstruction is the establishment of correspondences between the projections of 3D feature points in a scene. 

To this end, I have been interested in global optimization approaches to the matching problem. Up to this moment, my work has been centered on the use of rank constraints to achieve the correct correspondence.
