As an mi portantm eans for rem ote sensing mi age processing, mi age color enhancing techn ique can effectively mi prove the visual effect of the mi age, enhance the recogn ition rate of inform ation, and evidently mi prove the quality of remote sensing application. Accord ing to the function characteristics ofRGB, H SV andH SI colormodels, through the conversion expermi ent of these three models and graying expermi ent of color mi age, th is paper d iscussed the enhancing process ing m ethod of remote sensing mi age.
