The slit lamp biomicroscope is one of the most commonly used devices for retinal inspection, specially for the treatment of the eye periphery. However, only a small portion of the retina can be visualized through the biomicroscope, complicating the task of localizing and identifying surgical targets, increasing treatment duration and patient discomfort.

I am currently researching methods for creating intra-operative retina maps for view expansion using a slit-lamp device.

Computer vision tools can be developed to help persons with disabilities, improving current human-computer interaction systems. I have recently assisted in the development of a low-cost vision-based head tracking system for replacing current hardware based solutions.

We explore different similarity functions for improving direct gradient-based visual tracking. We have explored the properties of information-theroetical similarity measures for improving robustness towards illumination variations. We have also proposed occlusion detection techniques in the context of tracking using the Normalized Cross Correlation.
