Directionality-based speech enhancement for hearing aids
In this work we describe methods for using the directionality of sound energy as a criterion to estimate single- and multichannel linear filters for suppression of diffuse noise ...

Face shape recovery from a single image using CCA mapping between tensor spaces
In this paper, we propose a new approach for face shape recovery from a single image. A single near infrared (NIR) image is used as the input, and a mapping from the NIR tensor sp...
