Abstract

Band selection work is mainly focused on various kinds of vegetables. Two kinds of data are used in this work project. One is the spectral data measured with ASD spectrometer; the other is airborne Push-broom Hyperspectral Imager (PHI) data. The band selection work consists of three parts, bandwidth selection, wavelength range selection, and center wavelength selection. Bandwidths of filters should be in the range 25nm to 50nm because of the angle effect of the bandpass interference filters. Two factors, light source characteristics and the CCD spectral responsivity, confine the filter center wavelength range in the range from 410nm to 810nm.. Methodology used in the center wavelength selection work is spectral correlation-based approaches, maximum relative technique and the linear forward stepwise regression technique. Those two kinds of method have almost the same result. And they are relatively well distributed over the whole spectral domain.
