Hi Gopi,
I think you have probably already found it, but the GSOC project we have already identified mentors for in SciPy is here:
If
this is a project you are interested in then I would start thinking
about what the FFT interface would look like and reviewing some of the
past/present issues related to fftpack / FFT in SciPy. Please ask
questions you have related to that project here so that you can clarify
what would be involved in writing a successful application.
If
you have a different idea in mind you can propose it here, but you
should do that soon, because it will be necessary to determine if there
is interest from the SciPy team before you spend time coming up with a
detailed proposal. We have to determine if a project sounds feasible to
complete for GSOC and if appropriate mentors can be identified.
Ultimately, you will need to submit an application to SciPy between March 25th - April 9th.
