Hi, Cody may well be onto it. Use a micro to handle the coms with the WiFi unit initially, whichever you use. This will allow you to set up and download data on your link quickly.
You could then test your video processing algorithms on a PC first. In other words, break the project up into workable chunks. Then work on your FPGA. It is possible to get soft processors onto FPGAs, the code is out there, and SPI is trivial. There is also a lot of work been done with video processing on FPGAs, it's all out on the web. If it's a final year project, it's got to be more than cut and paste though,
cheers,
Richard
