| Abstract: | The technology of pseudo-color enhancement of digital image processing is applied to the field of metallographic analysis.The model of the mapping relation between gray level and pseudo-color is established,and the pseudo-color conversion system is designed,which can operate in microcomputer.The experiment shows that the conversion of gray image to pseudo-color image can be accomplished easily with this real-time pseudo-color conversion system.Thus the small gray level difference can be converted to the sharp hue shift clearly and the contrast of discrimination is improved greatly. |
