%X Several objective measurements of spectral distortion widely used in quality evaluation of spectral image compression were analyzed.Considering characteristics of spectral distortions,RQE was modified and a new distortion measurement method based on spectrum differential was brought forward.This method agrees with spectral image application,and it is extremely sensitive to the change of spectrum absorbing feature point.The experiment result proves that this method can measure spectral distortions effectively.
