Soil erosion is one of the most widely dispersed adverse geomorphological processes in a global scale. If it is not limited, it can change the topographic surface, reduce the slope stability and water retention capability, and thus increase the disposition for geomorphological hazards. Heavy rainfalls or intensive snowmelt are the main triggering factors for erosion, but the processes strongly depend on the topography, slope gradient, soil properties, vegetation cover and land use. The aim of the current research ...

COMPLEX APPROACH FOR TEXTURE AND MULTISPECTRAL SEGMENTATION OF HIGH RESOLUTION SATTELITE IMAGES

(Stef92 Technology, 2011-06-20, Veselina Gospodinova)

It is introduced a complex approach for texture and multispectral segmentation, based on texture analyses. The data fusion method is used for combining the multispectral and texture features of classes in the area s which is investigated. The texture features are estimated by the calculation of variance and skewness statistics over the windows with different sizes. The results ar e integrated with spectral chan nels of satellite images. The images from KOMPSAT-2 satellite are used for testing purposes. The spectra...
