Dear Colonel
at the Jet Propulsion
STAT
Laboratory, Pasadena, Calif., has developed some
computer programs for digital processing of the
lunar and Mars photos. He was remarkably success-
ful in improving image quality and actually increased
resolution considerably. His processing included:
a.)
Removing
geometric distortion
b.)
Removing
systematic noise
c.)
Localized
expansion of grey scale
d.)
Removing
photometric distortion
e.)
Inverting
the contrast transfer
function.
Although I loriginal video was in coarse
grained digital form, I believe we could readily
adapt the process to your fine grain continuous tone
material. Digital processing would not be a gen-
eral purpose tool as the present processing rate is
only 16 image ?oints per second. To process a
single 9" by 9' frame at this rate would tie up your
computer for a number of days.
The process would probably only be suit-
able to small sections of frames, perhaps one or
two square inches, which contain the most important
imagery. It would I think be a great boon to have
some powerful tools for the improvement of selected
images of extreme interest.
If you are not already actively exploring
I I work and would like to discuss this
r er, p ease give me a call.
Best regards,
