The F#.NET Journal just published an article about spectral analysis:
"The Fourier transform is one of the most important numerical methods and underpins most forms of spectral analysis. This article describes a simple image compression technique that uses the Fast Fourier Transform (FFT) to remove the high-frequency components of an image. The 2D FFT is efficiently parallelized and the resulting application provides a WPF GUI allowing the user to control the accuracy of the approximation..."
