Important Notes

In this lab, you will be using the ComplexFFTImage class. This is almost identical to the ComplexImage class, except it has a built-in FFT function. For example, if you want to transform the ComplexFFTImage image you only need to type in:

image.FourierTransform ();

And to reverse the transformation, you only need to type in:

image.InverseFourierTransform ();


Syntax for image interpolation. User specifies coordinates of top_left_row and top_left_column of rectangular region to be enlarged. Suggested command line usage:

For Image decimation, the suggestion is that you set up your program to use the following syntax:
