This file forms an estimate of the frequency spectrum using eigenvector algorithm (Johnson & DeGraaf 1990).

Based on negative entropy largest independent component analysis, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Can be widely used in data analysis and forecast data.

Achieve a grayscale image and further control for video surveillance, Dual-line interpolation FFT harmonic analysis kaiser windows, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition.
