Rainbow 5.08
Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameters and/or number of points may provide discrepancies.
See how zero padding effects your results. See 50+ dB weak signal detection.

2D FFT/iFFT plugin 1.0
User-friendly 2D FFT/iFFT (Fast Fourier Transform) plug-in for Adobe PhotoShop compatible plug-in hosts. It uses one of the fastest implementations of the Discrete Fourier Transform and has many applications including periodic noise removal and pattern detection. This can be very useful in analyzing fingerprints, paper sieve patterns etc.
