AN EFFICIENT APPROACH FOR EXTRACTION OF LINEAR FEATURES FROM HIGH RESOLUTION INDIAN SATELLITE IMAGERIES
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 4
Abstract
This paper presents an Object oriented feature extraction pproach in order to classify the linear features like drainage, roads etc. from high resolution Indian satellite imageries. It starts with the multiresolution segmentations of image objects for optimal separation and representation of mage regions or objects. Fuzzy membership functions were efined for a elected set of image object parameters such as mean, ratio, shape index, area etc. for representation of equired image objects. Experiment was carried out for both anchromatic (CARTOSAT-I) and multispectral (IRSP6 LISS IV) Indian satellite imageries. Experimental results show that the xtraction of linear features can be achieved in a satisfactory level through proper segmentation and appropriate definition & epresentation of key parameters of image objects.
