APPLICATION OF WAVELET TRANSFORM ON HYPERSPECTRAL REFLECTANCE FOR SOYBEAN LAI ESTIMATION IN THE SONGNEN PLAIN,

Research has indicated that biochemical components, physical structure, water content have intimate relationship with spectral reflectance[1]. Numerous vegetation indices have been developed to detect environmental conditions of crops, usually by calculating ratios or linear combinations of two or more wavelengths within the visible and near-infrared (VNIR) region. Thought hyperspectral remotely sensed data can provide more informatio
