We propose a new context-sensitive active contour for 2D corpus callosum segmentation. After a seed contour consisting of interconnected parts is being initialized by the user, each part will start to deform according to its own motion law derived from high-level prior knowledge, and is constantly aware of its own orientation and destination during the(More)
Computerized binocular infrared pupillography was used to measure the transient pupillary light reflex (PLR) in both children with autism spectrum disorders (ASDs) and children with typical development. We found that participants with ASDs showed significantly longer PLR latency, smaller constriction amplitude and lower constriction velocity than children(More)
We investigated the gender effects on transient pupillary light reflex (PLR) in healthy young adults between 18 and 22 years old. Both dark-adapted and light-adapted PLRs were measured using green and red stimuli of different intensities. The results indicate that females had significantly larger relative constriction amplitudes than males in a dark-adapted(More)
PURPOSE Contraction anisocoria describes a phenomenon in which the pupil of a directly illuminated eye constricts more than the pupil of the consensual (not illuminated) eye. The purpose of this study was to investigate the lateralization of contraction anisocoria in young female and male subjects. METHODS Infrared binocular pupillography was used to(More)
