| Summary: | The objective of this paper is to construct a real time
hardware image processing system on Field Programmable
Gate Array (FPGA). The chosen image processing
algorithm is a single Color Filtering algorithm. This work
utilizes Altera DE2 development board empowered by the
Cyclone II FPGA paired with a 1.3 Mega pixel CMOS
camera from Terasik Technologies. Verilog HDL is chosen
as the hardware programming language for this system and
its compiled using Quartus II program. The functionality of
the algorithm is first verified in Matlab, simulating the
expected output of the system before implementing it onto the FPGA development board. Two band-pass-filter-like
algorithms has been tested and implemented. The first is the
single band-pass filter with threshold selected according to
the International Commission on Illumination (CIE) values.
The second is the double band-pass-filter algorithm. Work is
currently conducted to quantify the effectiveness of the
band-pass filtering algorithm on FPGA before proceeding to
test and implement the triple and quadruple band-pass
filtering methods. |
