Introduction:
Signal processing concerns the use of computer technology to analyze, store, transform or
modify, create or synthesize, and interpret sounds, pictures, or other types of signals.
The Signal Processing and Analysis Center supports a wide range of research and
instructional activities, both theoretical and applied, in the broad area known as signal
processing. The Center consists of two major components: The Speech and Audio Processing
Laboratory and the Oklahoma Imaging Laboratory. These laboratories in the School of
Electrical and Computer Engineering at OSU contain extensive computational and support
facilities for use by faculty and students working on problems in signal processing. The
Center also provides an excellent foundation for supporting the signal processing
curriculum offered by the School.
Equipment and Facilities:
The Speech and Audio Processing Laboratory, directed by Dr. Keith Teague, supports the
digitization, processing, analysis and synthesis, display, and playback of audio bandwidth
signals. A variety of high-performance PCs and Sun Sparc workstations are available in the
laboratory, along with a number of commercial software packages. All systems support A/D
and D/A, and many contain special purpose signal processing hardware. Real-time algorithm
development is supported on signal processing development systems from Motorola, Texas
Instruments, AT&T, and others. Some of the special purpose processors which are
supported by development systems in the laboratory are DSP56002, DSP56166, TMS320C25,
TMS32C30, TMS320C80, and DSP32C.
The Oklahoma Imaging Laboratory, directed by Dr. Scott Acton, contains several platforms
for image processing including RISC-based workstations, PCs, high quality laser printers,
analog cameras, digital cameras, an infrared camera, scanners, and digitization hardware.
Specifically, image processing research is conducted on Sun Sparcstations and Power
Macintosh computers which have the capability to digitize video signals and to produce
video output.
Areas of Interest:
The Center is supported from a variety of internal and external funding sources. Some
current notable research projects include 1) Image Coding and Speaker Recognition (U.S.
Army Research Office), 2) Automated Target Identification and Tracking Algorithms for the
Next Generation of FLIR Systems (U.S. Army Research Office), 3) High-Quality 2400 bps
Speech Coding (Department of Defense, Digital Voice Processor Consortium, 4) Automated
Circuit Inspection (Lucent Technologies), 5) Infrastructure Inspection and Remote Sensing
Applications (local industries), and others.
Instruction and Related Courses:
The School of Electrical and Computer Engineering offers a variety of courses covering a
wide range of topics relevant to signal processing. Center facilities are used in many
cases to support this instruction, along with specific student projects which require
special-purpose equipment available in the Center.
Some of the courses which have been offered recently are Discrete Time Signals and Systems
(ECEN 4763), Real-Time Digital Signal Processing (ECEN 4773), Digital Signal Processing
(ECEN 5763), Image Processing (ECEN 5793), Digital Processing of Speech Signals (ECEN
5753), Machine Vision (ECEN 5283), and Low Bit Rate Speech Coding (ECEN 5050). Additional
courses in related areas such as neural networks, data communications, remote sensing, and
others are also offered regularly.
Students:
Doctoral and Masters students, and a limited number of undergraduates, are involved in
most research projects carried on by Center personnel.
