A method of image processing. An expected band-averaged spectral radiances image vector is simulated from training hyperspectral data and at least one filter transmittance function corresponding to the at least one optical filter. A simulated measured band-averaged spectral radiances image vector is simulated from the training hyperspectral data and the at least one transmittance function. A realistic measured band-averaged spectral radiances image vector is provided from at least one optical filter. A cross-correlation matrix of the expected band-averaged spectral radiances image vector and the realistic measured band-averaged spectral radiances image vector is calculated. An auto-correlation matrix of the simulated measured band-averaged spectral radiances image vector is calculated. An optimal out-of-band transform matrix is generated by matrix-multiplying the cross-correlation matrix and an inverse of the auto-correlation matrix. A realistic recovered band-averaged spectral radiances image vector is generated by matrix-multiplying the optimal out-of-band transform matrix and the realistic measured band-averaged spectral radiances image vector, the realistic recovered band-averaged spectral radiances image vector being free of out-of-band effects. |
