Implementation of a semi-automatic method of feature extraction, based on the active contour method or ‘snakes’, will be described and results obtained from the procedure demonstrated The paper will define the method of snakes for 2 dimensional features on single images, and 3 dimensional features on two or more images. The results of tests on SPOT satellite images are described in terms of the accuracy of the extracted features and pull-in range, for a range of features, for both 2 dimensional and 3 dimensional geometry.
