Abstract
Imaging
features
may
appear
blurred,
distorted
or
mixed
with
noise
in
the
process
of
scene
imaging.
As a
consequence, quality of images is lowered,which in digital images is likely to make it difficult to identify the target
image or to extract the image features, images must be restored, then. Wiener filter is a common method for image
restoration.This
paper
mainly
introduces
the
basic
principles
of
Wiener
filtering,
and
function
of
MA
TLAB
are
combined
to design
the
corresponding
Wiener
filter
to
restore motion-blur
images.
And
noise
restoration
are
also taken into account in the design.Finally, the inverse filter and Wiener filter for image restoration simulation
experiment be taken, and compared the differences between them.
Key words
: Wiener filter; image restoration; degraded image
