| Abstract: | By using ENVI image processing system, applying color space transform respectively, ratio transformation and principal component transformation method, multi-spectral images and panchromatic band images gained by using aerial DCM camera have been fusioned. Using subjective analysis and quantitative comparison method, from the visual angle and the angle of statistical index, the advantages and disadvantages of 3 kinds of image fusion methods have been carried out respectively. It is regarded that color space transformation method has better effect. It will provide the basis for high DCM image enhancement processing. |
