The Electronic Systems and Signals Research Laboratory (ESSRL) was formed
during the 1986-87 academic year. This laboratory brings together
researchers within the Department of
who have common research interests, and common resource needs.
The laboratory has evolved from occupying
a single room on the third floor of Bryan Hall to occupying the entire
fourth floor of Jolley Hall.
ESSRL is an academic research laboratory pursuing complementary
educational and research activities.
The primary role of ESSRL has been to provide an environment
within which faculty, students, and staff can pursue their research,
and an infrastructure for assisting them in achieving their goals.
Many of the projects within ESSRL involve connections with real
problems, development of statistical models that characterize data
available, development of analytical tools and algorithms for these
problems, and implementation of the algorithms. The director of the
Imaging Science and Engineering
academic program is in ESSRL.
The faculty within ESSRL have participated in collaborative research
projects since its inception. Within the university, many of these
collaborations have been with the School of Medicine; others have been
with departments in Arts and Sciences, and with faculty throughout
the School of Engineering and Applied Science. There are many
existing collaborations with researchers outside Washington
University, from universities, industry, and government.
Imaging science plays a central role in the research within ESSRL,
with six of the faculty pursuing imaging research. ESSRL is a
leader in quantitative image processing, dynamic vision, and
statistical image and signal processing. Applications range from
medical imaging (including CT, ultrasonic, and optical) to commercial
In addition to the imaging and vision research, there are active
projects in information theory and its applications, array processing,
electrocardiography, and VLSI system design.
Please take a few moments and look over our web pages where more
detail is given on individuals and their research. If you
would like any further information, please do not hesitate to
contact me or any of the researchers directly.

Research in ESSRL is pursued in collaboration with many parts of Washington
University, other universities, and with industry. Strong ties in biomedical
research exist with the Departments of
Anatomy and Neurobiology,
and Physical Therapy of the
School of Medicine
and with the
Institute for Biomedical Computing.
Intra-university collaborations exist with the
Department of Mathematics
University of Chicago,
Department of Mathematics
Georgia Tech Research Institute,
Mobile Communications Center
University of South Australia,
Space Telescope Science Institute
Johns Hopkins University.
Current research in ESSRL emphasizes both theory and application. Topics
include: model based digital and analog signal and image processing; stochastic
process theory, modeling, and applications; shape theory, modeling, and
applications; communication and information theory; coding theory; bandwidth
and energy efficient modulation schemes; multiaccess communications;
estimation and decision theory; radar and infrared systems and their
use in imaging and automatic target recognition; low light level
optical imaging; restoration of optical images degraded
by aberrations and atmospheric turbulence; tomographic
imaging; ultrasonic imaging and tissue characterization; anatomical mapping;
statistical signal processing for sensor arrays; and computational
Extensive resources are available to pursue research in ESSRL. This laboratory
occupies 8000 sq. ft., which houses faculty and student offices, rooms for
computer terminals and graphics workstations, a computer equipment room, an
electronics shop, and a conference room. General computing resources include
several SUN workstations, a DEC 3100 workstation, two DEC 5000 series
workstations, and Silicon Graphics workstations. In addition, ESSRL is a
center for parallel computation in image processing with its DEC MPP-12000
parallel processor having 8192 processing elements. ESSRL is connected to
the rest of the University campus via a wideband computer-communication
network. Research grants and contracts exist with the
National Science Foundation,
National Institutes of Health,
Office of Naval Research,
Army Research Office,
Air Force Rome Laboratory.
