Abstract	:	Using a coding theoretic approach, we achieve unsupervised image segmentation byimplementing Rissanen's concept of Minimum Description Length (k1DL) for estimat-ing piecewise homogeneous regions in images. MDL offers a mathematical foundationfor balancing brevity of descriptions against their fidelity to the data. Our imagemodel is a Gaussian random field whose mean and variance functions are piecewiseconstant. Our model is aimed at identifying regions of constant interlsity (mean) andtexture (variance).Based on n multi-scale encoding approach, we develop two different segmentationschemes. One algorithm is based on an adaptive (greedy) rectangular partitioning,while the second algorithm is an optimally-pruned wedgelet-decorated dyadic parti--....,....-...,..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..
