Faster and more accurate face detection on mobile robots using geometric constraints
— We develop a framework to allow generic object detection algorithms to exploit geometric information commonly available to robot vision systems. Robot systems take pictures wit...

Segmenting the prostate and rectum in CT imagery using anatomical constraints
The automatic segmentation of the prostate and rectum from 3-D computed tomography (CT) images is still a challenging problem, and is critical for image-guided therapy application...

Rigid Motion Constraints for Tracking Planar Objects
Typical tracking algorithms exploit temporal coherence, in the sense of expecting only small object motions. Even without exact knowledge of the scene, additional spatial coherence...

Human Movement Performance in Relation to Path Constraint - The Law of Steering in Locomotion
We examine the law of steering – a quantitative model of human movement time in relation to path width and length previously established in hand drawing movement – in a VR loc...
