Gianpaolo Palma received the Ph.D in Computer Science from the University of Pisa in June 2013 with a thesis about the estimation and reconstruction of the surface appearance of real objects using one or more video sequences acquired in uncontrolled and arbitrary lighting conditions. The main focus of the thesis was to enrich the photo-realistic rendering of a 3D model of the acquired object. Since 2009, he has joined the Visual Computing Laboratory of the ISTI-CNR at Pisa as Graduate Fellow. His main research interests are the image-to-geometry registration, the video analysis, the surface appearance acquisition and estimation. He is the main designer and developer of RTIViewer, the current multi-platform tool for the interactive visualization and manipulation of RTI (Reflectance Transformation Imaging) images, and WebRTIViewer, an HTML5 web application to improve the dissemination on the web of the RTI images.
