This paper describes a program developed to allow semi-automatic detection and enhancement of linear features in aerial photography. The program employs three different edge detectors namely Sobel, Deriche and Canny as well as morphological operations. The effectiveness of each of these operators and mathematical morphology is compared. Classification(More)
