Sylvain’s work focuses on extracting information from photographs and videos. His goal is to obtain useful data for Computer Graphics, i.e. suitable for rendering new images. During his PhD with François Sillion at INRIA, he developed new solutions to image-based modeling, mainly shape reconstruction from image sequences, and recovery of the 3D geometry of hair.
Since his post-doc at MIT with Frédo Durand, he has been interested in computational photography. He is looking at signal-processing techniques to apply them to digital photographs and videos. Compared to traditional film photography, this unveils a large spectrum of possibilities to modify and enhance the picture content. Conversely, photography-related applications raise specific issues such as user interaction and photorealism, and cast a new light upon known signal-processing methods.
He is currently a researcher at Adobe, working in the Advanced Technology Labs where he is pursuing research on computational photography and image-based modeling.
