The discrete wavelet transform as a precursor to leaf area index estimation and species classification using airborne hyperspectral data
The need for an efficient dimensionality reduction technique has remained a critical challenge for effective analysis of hyperspectral data for vegetation applications. Discrete wavelet transform (DWT), through multiresolution analysis, offers oppurtunities both to reduce dimension and convey inform...
