Abstract The filtering scales of different edge models axe different in edge detection. The effective scales of different edge models based on compact,symmetry and smooth function are discussed in detail. The effective scale ranges of Gauss function and cubic B spline function to restrain noise are analyzed also. The conclusions of this paper are important in multiscale edge detection, and are the theoretic base of scale choice in edge detection.
