Abstract	:	This dissertation explores the use of texture for modelling geospatial objects inremote sensed images. Texture based analysis of remote sensed images has not en-joyed the same success as spectral based analysis. This is surprising since texturecan be considered as context at the pixel level, and context is acknowledged to beimportant for analyzing geographic data. This work extends texture based analysisbeyond land cover classification, which can be viewed as the current state-of-the-art,to modelling objects composed of multiple characteristic textures or texture motzfs.A statistical pattern recognition framework is adopted in which the texture motifsare modelled as mixtures of Gaussians in the high dimensional texture feature space,and the model parameters are learned in an unsupervised manner using the expecta-tion maximization algorithm. The objects and their motifs are assumed to occur atarbitrary orientations in the images which presents a formidable challenge to using..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
