My research is in Computational Vision. I am studying from a computational point of view the processes involved in interpreting images. Most of my work has been concerned with obtaining information from video sequences and stereo images. Within this area I have worked on many problems, including the computation of image motion, three-dimensional motion estimation, reconstruction and shape estimation, and segmentation of the scene. There are many areas of technological applications for this research; I have worked on video data bases, robotic navigation and surveillance. My recent efforts have been on the design of new camera systems exploiting multiple views.

From a scientific perspective my work can be seen as the use of mathematics and computation to shed light on the structure and function of the early visual processes in the brain. I have applied my theoretical findings to explain aspects of biological vision, known from Psychophysics and the Neurosciences. For example, I have explained recently a large number of optical illusions. Currently I am working on the feedback loops linking three-dimensional shape, motion and segmentation. I perceive the study of Vision as a highly interdisciplinary activity. Mathematics and computations can tell us what is possible, but we need inspiration from nature on what we should study.
