RESEARCH

My passion is the discovery of hidden relationships in data containing a large amount of variables in comparison with a small number of observations. This falls in the field of statistical analysis with an emphasis on dimensionality reduction for building a more suitable representation for the data. Besides other applications such as humanoid robotics, I have applied dimensionality reduction techniques in two main areas of computer vision: Shape Analysis and 3D reconstruction. Recently, I have also started research collaborations related with cognitive sciences for computer vision and robotics as well as applying computer vision and statistical models for plant and soil studies through deep learning.

3D face shape recovery from occluding contours

For many shape analysis problems, I believe that coupled variations provide a more suitable way for understanding the nature of data and the hidden language of the variables involved in the studied phenomena, as in this statistical model of shape and texture for 3D face shape recovery from 2D contours.

Extended photometric analysis

This research has been focused on a photometric stereo approach that is exclusive for face shape recovery, seeking for a coherent way to keeping facial proportions when estimating shape from several 2D images.

3D object reconstruction from a humanoid generated video sequence

I have worked on the development of geometric approaches for the monocular-based localization of humanoid robots, finding applications in both navigation and object reconstruction tasks.

Persisten localization of a humanoid robot

Robot localization is an important skill in the quest for autonomy. I have explored using Principal Component Analysis to lead the robot to safer directions for keeping a healthy localization.
