Abstract With the development of remote sensing digital image processing and pattern recognition, visual interpretation is still the most important method to extract the information of the image. In the remote sensing, the best three bands can be selected from the multi band, and can not only compress the amount of data, but also can achieve the purpose of enhancing the effect of the image interpretation.. The OLI sensor to carry on Landsat-8 (OPEX land imager) images, the information content of band selection evaluation method, optimal index method (optimal index factor OIF) analysis of Yunlong Lake in Xuzhou, China OLI image information expression based on found optimum band combination for 765, the OIF index value for 1823.06, after according to the different feature types of band selection, and then use of optimal index method defects make improved adaptive band selection method (adaptive band selection, ABS) for band selection, obtained optimum band combination of 优尔, the ABS index value is 2348.93. The classification effect of the synthesized images of the two bands selected by the combination of the band combination is analyzed.
Key words: Multispectral; color synthesis; optimal bands selection; Image interpretation; Optimal Index Factor
