Towards the use of diffuse reflectance spectroscopy for real-time in vivo detection of breast cancer during surgery

Background: Breast cancer surgeons struggle with differentiating healthy tissue from cancer at the resection margin during surgery. We report on the feasibility of using diffuse reflectance spectroscopy (DRS) for real-time in vivo tissue characterization. Methods: Evaluating feasibility of the technology requires a setting in which...

Sign Language Recognition by Combining Statistical DTW and Independent Classification

To recognize speech, handwriting, or sign language, many hybrid approaches have been proposed that combine Dynamic Time Warping (DTW) or Hidden Markov Models (HMMs) with discriminative classifiers. However, all methods rely directly on the likelihood models of DTW/HMM. We hypothesize that time warping and classification should be separated...

Real-Time Multi-Step View Reconstruction for a Virtual Teleconference System

We propose a real-time multi-step view reconstruction algorithm and we tune its implementation to a virtual teleconference application. Theoretical motivations and practical implementation issues of the algorithm are detailed. The proposed algorithm can be used to reconstruct novel views at arbitrary poses (position and orientation) in a way...
