The Eye and its Environment: Geometric Analysis of Corneal Reflections, Christian Nitschke
Sprache des Titels:
An image of the human eye does not only capture its anatomical features, but also the environmental light distribution reflected in the cornea. Recently, it has been shown that the combination of camera and cornea can be modeled as a catadioptric imaging system to extract a person?s view and incident illumination at the eye. We want to go further and discuss that integrating multiple eye and scene images establishes a relation between the individual (eye) and its environment, which naturally overcomes inherent problems and enables novel solutions in eye analysis, scene understanding, and human-machine interfaces. However, this demands for specialized algorithms to handle and exploit the complex geometric and photometric properties of the human eye, leading to various challenges in feature tracking and geometric modeling. This talk will provide a comprehensive overview about the topic of geometric eye modeling and corneal reflections analysis, with a focus on the speaker?s own developments, covering motivation, algorithmic pipeline, novel applications, and promising future directions.
