Our main research interest is computer vision and image analysis. In that framework, we have worked on image registration, image segmentation, visual object tracking, image and feature registration and modeling, image super-resolution, human activity recognition and handwritten character recognition. An important part of our research is also focused on models and methods for biomedical imaging. Specifically, we have been studying methods for single and multimodal brain image registration and statistical models for the analysis of brain images. Also, we have proposed methods for the detection and analysis of cell nuclei in Pap smear image analysis.
