An Analytical Solution to the Perspective-n-Point Problem for Common Planar Camera and for Catadioptric Sensor
The Perspective-N-Point problem (PNP) is a notable problem in computer vision. It consists in, given N points known in an object coordinate space and their projection onto the ima...

Sonar-based measurement of user presence and attention
We describe a technique to detect the presence of computer users. This technique relies on sonar using hardware that already exists on commodity laptop computers and other electro...

Stereo matching with asymmetric occlusion handling in weighted least square framework
This paper presents a novel method for stereo matching with occlusion handling. In order to estimate optimal cost, we define an energy function and solve the iterative equation w...
