An Entropy-Based Method of Background and Noise Removal for Analysis of Near-Infrared Spectra

A new algorithm (WFCE) was proposed for simultaneously eliminating background and noise based on wavelet packet transform (WPT) and information entropy theory. At first, WPT algorithm and reconstruction algorithm were employed to split the raw spectra into different frequency components. Then the in...
