Cable Avoidance Study.

Abstract : The problem of real-time wire extraction from video scenes for helicopter navigation is addressed. A combination of semi-linear local line detectors and semi-local line discriminators is developed to optimize detection and false alarm rejection. While the results are quite good, further software development is indicated to improve both detection and noise rejection for pilot displays. Two directions for further development are suggested. A video tape demonstration of the current algorithm applied to scenes containing cables accompanies this report. (Author)
