    Its a convolution/deconvolution problem. All you need to do is to implement
    the algorithm in Java and then find the appropriate matrix to perform the
    task. Sorry to say, I don't know what would be the best matrix to use.
    Michael Covington's book has an overview of the process.

    Most of us are more interested in not buying lenses with significant amounts
    of either flaw. So, we don't know.

  3. Check out the freeware panorama tools software. This already does
    this. But the code is available as well so you can copy and/or
    adapt for your purposes if you need something different.
