Abstract—In recent years, the image processing intelligent based systems has been the subject of interest for many researchers. In this manner, interpretation of urban aerial hyperspectral textured images is lionizing due to special features of this images. Image segmentation is the first step to reach this aim and extract features of these images. The correct selection of spectral bands is very important, because of multiplicity of spectral bands in this images and variety of texture in each of spectral bands. Since not all spectral bands include useful information, taking into account all of spectral bands decreases the speed of processing and accuracy of segmentation. In this paper, several dimension reduction or in other words spectral band reduction approach studied. In addition, the effect of each dimension reduction algorithms on accuracy of segmentation represented.
