EVALUATION OF VARIOUS SEGMENTATION TOOLS FOR EXTRACTION OF URBAN FEATURES USING HIGH RESOLUTION REMOTE SENSING DATA

temporal modelling, Spatial data modelling, decision support The study involves segmentation of the image using the three segmentation modules of three software namely ERDAS Imagine, ENVI and eCognition to extract building features. The best parameters for segmenting buildings have been established. New method of evaluation has been presented for evaluating segmentation quality. The results of three segmentation modules are assessed using the proposed evaluation methodology and the results are discussed. A general comparison of the three tools is also provided at the end
