【 摘 要 】
Vegetation high-resolution image segmentation is an important kind of target, while how to fuse image by using spatial and spectral information of GeoEye image, and make effective determination of the scale of vegetation texture segmentation is an important topic. This paper presents an algorithm of GeoEye image fusion vegetation information extraction based on blue noise measurement texture, which the vegetation information spectral response is calculated based on fast Fourier transform, in order to obtain the texture gray scale distribution of vegetation information, thus realizing accurate extraction of vegetation information. The simulation result got by the algorithm shows the deviation between NDVI index and original value index is below 0.05, which is obviously better than those obtained with the two comparison fusion algorithms of PCA transform (smaller than 0.4) and Brovey (smaller than 0.25), and provides the best parameter combination form [120,0.34,0.48]. Hence, it is an effective algorithm for high accuracy GeoEye image vegetation information acquisition.【 预 览 】
