ABSTRACT
A technique that integrates applications of wavelet packets and principal component analysis is developed. This technique is applied for the purpose of detecting anomalies in Fourier Transform Infrared (FTIR) interferograms. An experimental example is given to demonstrate the performance of this technique.
