Moment-preserving curve detection
L.-H. Chen, W.H. Tsai · IEEE Transactions on Systems Man and Cybernetics · 1988
A novel method for curve detection based on the moment-preserving principle is proposed. The method can be used to estimate curve locations and widths to subpixel accuracy. For each 4.5-unit circle in an input image that includes a curve segment, the approach derives a parabolic equation as well as a width value to describe the curve segment. Experimental results are included to show the effectiveness of the proposed detector.>
