Medical X-rays
Fig1: This curious image is a digitized x-ray
of a
muscovy duck. It provides a demonstration of a restoration on a
non-optical
image.
Run your mouse
over the
image to reveal the restored figure.
Fig 2: Restored Image. As you can
see, much greater detail is seen when the degration is removed.
(The straight line on the right was not orignially imaged, but
superimposed for demonstrative purposes. Thus it appears
distorted after deconvolution.)
Fig1: This is a digital dental panoramic
X-ray of human teeth. The original image had a bit depth of 8 bits, and
had jpeg compression.
Run your mouse
over the
image to reveal the restored figure.
Fig 2: Restored Image. Despite the low bit
depth, the resolution of this image
is drastically improved. However, if you closely at the gray areas, you
can see some artifacting that results
from the jpeg compression.
Fig1: This is another digital X-ray of
teeth, pretty typical of all digital X-rays found on many
websites.
Run your mouse
over the
image to reveal the restored figure.
Fig 2: Restored Image. The deconvolved image
was noisy. So we applied
a noise reduction filter to reduce noise and emphasize the main
features.

Fig1: This image is an
x-ray of a penguin.
Run your
mouse over the
image to reveal the restored figure.
