Abstract:
This paper examines the gradient-based edge
detection algorithm on hexagonal grids and
compares it with that on conventional
rectangular grids. Since there is no mature
hardware for hexagonal-based image capture
and display, our research work is based on the
newly proposed mimic scheme, called virtual
Spiral Architecture, which is demonstrated to
make the research work based on hexagonal
image processing practically workable on
current hardware. From our experiments, it is
found that a better edge map can be obtained
using this architecture than using the square
architecture.
