1. This proposal is well-written; it indicates that the writer
is fairly well acquainted with the technique he proposes to research.
I feel that he is charging over ground already charged over by
(SPPL) in a study of image quality following successive printings. It
is reasonably easy to calculate for simple images, and generally
follows subjective judgements of quality.
3. The writer has made several errors, not serious. On page 11-9,
he treats spatial frequencies, but in reality is talking of s
atial
p
details in the photograph. These are certainly related to spatial
frequencies, but so is the gross detail. I think he might have
difficulty using the same sentences if this change of meaning were forced
upon him.

but there may be some minor emphasis I have missed.
2. I agree with the method of image assessment -- fidelity defect.

4. The reader is promised that this research program will result
in blur-correction techniques. Nowhere is he treated to a discussion of
how blur affects contrast and how the spread function of this blur will be
corrected, changed, amended, or what have you. I felt like someone was
dangling a carrot in front of me, and pulling it away each time I was
ready to take a bite. I don't know whether or not this was deliberate,
resulted from a lack of sufficient arguments or knowledge, or was a
red-herring accidently dragged across the path. I certainly would suggest
we ask them specifically to define how they propose to de-blur images. At
least define what it is they mean by a blurred image.
5. I feel the proposal represents a program which could be adequately
carried out by the proposed personnel. I also feel that a more detailed

I further think they should discuss the principle and how
their proposed program differs from that technique. A
