Research Description

Digital signal processing, communication theory, information theory, neural network models applied to pattern recognition and analysis.

Ongoing research has been directed toward:

1. A digital model for the human hearing system, representing the transfer function between incoming acoustic pressure and electrical output to the auditory nerve. This research focuses on intelligibility issues for the normal and hearing-impaired individual and also the application of adaptive noise suppression
2. Image data compression applied to synthetic array radar, infrared images, television data and ordinary photographic images. This research focused on methods for recognizing targets in images and in aligning features in images
3. A computational technique that exploits a compression of "lossy" data to reduce computations required for any system with linear processing.
