Limbus misrepresentation in parametric eye models

Parametric Eye Models

The shape of anatomic objects often depends in complex ways on the shapes and locations of neighboring objects. Shape parameter networks provide an approach for representing shape dependencies and producing multi-object models that share consistent boundary definitions. This paper provides an overview of the modeling framework provided by shape parameter networks, and demonstrates their use thr...

Horizontal space misrepresentation in unilateral brain damage. II. Eye-head centered modulation of visual misrepresentation in hemianopia without neglect.

We used a visual distance reproduction task (endpoint task) to evaluate horizontal space representation in two left brain damaged (LBD) and three right brain damaged (RBD) patients with contralateral homonymous hemianopia and no neglect. All patients were examined in the chronic phase of the stroke and were aware of their visual field defect. Along with contralesional deviation in the line bise...

Misrepresentation in District Voting

Voting systems in which voters are partitioned to districts encourage accountability by providing voters an easily identifiable district representative, but can result in a selection of representatives not representative of the electorate’s preferences. In some cases, a party may have a majority of the popular vote, but lose the elections due to districting effects. We define the Misrepresentat...

Dual-State Parametric Eye Tracking

Most eye trackers work well for open eyes. However, blinking is a physiological necessity for humans. Moreover, for applications such as facial expression analysis and driver awareness systems, we need to do more than tracking the locations of the person’s eyes but obtain their detailed description. We need to recover the state of the eyes (i.e. whether they are open or closed), and the paramet...
