oiExtractWaveband - Extract wave bands from the scene oiW = oiExtractWaveband(oi,waveList,illuminanceFlag) The list of evenly-spaced wavelengths, waveList in nm, is extracted from the original optical image (OI). The output OI contains the photons in the wavelength bands. By default, the new OI does not have a calculated illuminance, and in fact its illuminance differs from the original OI. To re-calculate the illuminance, set the illuminanceFlag to 1. Note that the sensorCompute function often requires an illuminance if the auto-exposure algorithms are used. If the waveList is a single value, the spectral bin width is set to 1. Otherwise it is set to the difference in the (evenly spaced!) wavelength list. Example oiMonochrome =oiExtractWaveband(oi,500); oiMonochrome =oiExtractWaveband(oi,500,1); %Compute illuminance Copyright ImagEval Consultants, LLC, 2005.
