Nonnegative Matrix Factorization (NMF), which decomposes a target matrix into the product of two matrices with nonnegative elements, has been widely used in various fields of signal processing. In visual signal processing, the spatially nonuniformed distribution of perceptually meaningful information in image and video frames calls for a kind of Spatially-Weighted NMF (swNMF) that applies location...
Temporal psychovisual modulation (TPVM) is a new information display technology which aims to generate multiple visual percepts for different viewers on a single display simultaneously. In a TPVM system, the viewers wearing different active liquid crystal (LC) glasses with varying transparency levels can see different images (called personal views). The viewers without LC glasses can also see a semantically...
In this paper, an acoustic and visual signal based context awareness system is proposed for a mobile application. The proposed system senses and determines, in real time, user contextual information, such as where the user is or what the user does, by processing signals from the microphone and the camera embedded in the mobile device. An initial implementation of the algorithms into a smart phone...

Targeted for highly sophisticated visual signal processing, we introduce in this paper complexity metrics or measures of algorithms which featuring architectural information are feedback or back annotated in early design stages to facilitate concurrent exploration of both algorithmic and architectural optimizations. With application to 3D spatio-temporal motion estimation for video coding, we have...
