Research Interests

In the last decade, the use of pictures and the employment of cameras as sensing devices has become ubiquitous. My research seeks to develop image analysis techniques that support the effective use of imaging technologies in their ever-expanding employment in diverse application fields. Through the years I have focused on using physics-based color and reflectance techniques in the analysis of images. My early work addressed more classical problems in computer vision, such as shape reconstruction from a stereo pair of cameras and the computation of scene attributes that remain constant under geometric transformations and/or varying imaging sensors. Later work evolved around the use of novel sensors like multispectral cameras and magnetically-guided capsule endoscopes. In the last five years, while I continued investigating some basic computer vision problems like color constancy and intrinsic imaging, I became more involved in applied projects, partly in response to the omnipresence of imaging devices. Some of my more recent projects are on: image forensics, handwriting analysis of medieval documents, video-based surgical drill guidance, short-term forecasting of solar radiation, and navigation of autonomous vehicles.
