Date of Defense 2004-05-06 Availability unrestricted Abstract In this thesis, I present a design of a small, self-contained, underwater plankton imagingsystem. I base the imaging system’s design on an embedded PC architecture based on
PC/104-Plus standards to meet the compact size and low power requirements. I developed a
simple graphical user interface to run on a real-time operating system to control the imaging
system.
I also address how a real-time image compression scheme implemented on an FPGA chip
speeds up image transfer speeds of the imaging system. Since lossless compression of the
image is required in order to retain all image details, I began with an established
compression scheme like SPIHT, and latter proposed a new compression scheme that
suits the imaging system’s requirements. I provide an estimate of the total amount of
resources required and propose suitable FPGA chips to implement the compression
scheme. Finally, I present various parallel designs by which the FPGA chip can be
integrated into the imaging system.
