英文摘要：

This paper presents the principle of tactile image display technology based on jet stimulation.A kind of simply and faster image processing method is needed for tactile image display system.From traditional Otsu binary algorithm,the algorithm about not one region segmentation based on contrast stretching is introduced.This method for gray image is enough to tactile display with jet stimulation and useful to research work in the future.
