Dear Colonel I I
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 riginal video was in coarse STAT
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 points 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
work and would like to discuss this STAT
r er, p ease give me a call.
