There are couple of issues with this.

  1) Image processing is a huge field, so we would need
  a firm plan about what to put in and what to leave out.

  2) It will rely on ffts. If you followed the recent discussion
  on the mailing list about interfacing to FFTW and the status
  of the GSL ffts (starting with a message from Steven Johnson
  on Mar 16), then you know that things are a little unsettled.


  The ultimate idea, in my opinion, is to have some kind of
  compatibility layer so that users can choose which ffts to
  use, possibly by choosing at link time in the same way that
  a BLAS library is currently chosen at link time.

  If the ffts are all invoked in "user space" (explicitly),
  then the image processing does not introduce extra problems.
  For reasons of flexibility and simplicity, this might be a
  good goal for the design. It may not be possible to achieve
  this perfectly, and it may not be a problem at all, as long
  as the compatibility layer works well.

  In any case, we have to solve the problem of creating
  a compatibility layer for the ffts. This may be a tedious
  way to start the project, depending on your interests, but
  I think it is really important at this time. Once something
  is in place, then creating a higher layer of spectral
  applications should be very pleasant.

  What do you think?


Thanks.
