This is my solution for problem set 1. When you select the
frequency menu you will see the image transformed through an FFT algorithm. The
resulting image shows only the real data. Selecting spatial will reverse the transform.
There are 3 available draw modes.
Typing a filename into the textfield and hitting return will load an available image so long as it is within the security constraints of the applet. I have included one other image to use for demo purposes: laeca.jpg. If you wish to reload the original image it is called grantpark.jpg.
