Abstract In order to applying IHStransform to change detection, first use linear aggression to perform Icomponent and high spatial resolution PANradiometric rectification to minimize noise and variation caused by the difference of sensor type and imaging time. Then use coefficent overlay method to create a new Icomponent for inverse transform. This method improves the fusion result and enhance the change information for classification.
