|Code Listing by Harald E. Krogstad|
The note explains in detail how to apply the Matlab 2-dimensional FFT for filtering of two-dimensional signals, e.g. images.
It is shown how to connect the output from fft2 to the actual Fourier transform of the signal, and in particular how transfer functions of simple filters may be coded.
The note describes a simple m-file for digitizing graphs in the form of bitmap images using the Matlab ginput mouse pointer.
Axes are allowed to be skewed, as well as linear and/or logarithmic.
