ver urgent: image enhancement algorithms project

I wish to do a project on image enhancement using frequency domain analysis and realise using software and later hardware.I need to do the software realisation first. I wish to do the source coding in c/c++ and the front end in visual basic. I want to first convert image into its image transform using fourier analysis. Then i want to apply one of the following filters:
low pass
band pass
high pass
homomorphic
Then to the output image transform i want to apply inverse fourier transform to get the enhanced image. I would like to show the four images (input image, transform,output transform and output image) together on screen.

I would like to know how to go about it. I want to know books and websites where i can learn about these. I would like to know where i can get source codes which i can modify for my use.I am in quite a hurry to do this project. Any suggestions would be most welcome.
