The Saccadic Search Home Page

The Gabor Decomposition is a classical tool in Computer Vision. However, Gabor features are computationally expensive and are therefore often considered ill-suited for active-vision applications. The Saccadic Search algorithm we propose is a bio-inspired approach to fast Gabor Decomposition based pattern recognition.

The limitations of a common, plain GD based algorithm can be overcome by integrating two main inputs from biology, namely

The human saccadic system
The arrangement of photoreceptors in the retina

The integration of these two concepts into the common GD based algorithm constitutes the Saccadic Search strategy.

A few applications of Saccadic Search are presented here (for more details, please have a look at our publications online):

Facial Features detection (this also employs SVMs)
Face Authentication (SVMs also used here)
Real-Time Head Detection and Tracking (features a novel eyeball-mounted camera developed by the Biovision and Robotics Group at of the former Microprocessor Systems Laboratory at EPFL)

The Facial Features detection and Face Authentication algorithms have also been implemented in the VIRSBS project demonstrator, showcased at the Information Society Technologies (IST) exhibition in Vienna (Austria) in 1998.
