Research
Interest
My research interest is
directed at the study of depth perception and stereopsis, 3D vision and
binocularity from the approach of Cognitive Neuroscience and Psychophysics. I am
particularly interested in enhancing our understanding of the three-dimensional
space representation in the brain.
How the binocular
disparity is coded and computed in the Visual System?. How, through a sequence
of fixations of the gaze, we obtain the 3D structure of any scene. In order to
achieve this aim I have used a variety of methods such as:
- Computational
simulation of some visual processes. For example, model neurones tuned to
binocular disparity.
- Global and Local
Spectral Analysis, included wavelet transform. For example to match features
between left and right stereo images, having the same energy (luminance) spatial
frequency and orientation, but different phase.
- Psychophysics
methods. For example, compare estimations of properties of the stimuli in the
real world with those in virtual space.
- Computer design
of virtual worlds based on Virtual Reality technology. For example, obtain data
of gaze fixations by eye tracking technology.
- Exploring a
virtual space. For example, reconstruct a scene from a number of views showed to
the subjects.
