Abstract

We present a unified scheme for detecting digital components of various planar curves in a binary edge image. We introduce a measure d to reflect the complexity of a family of curves. For instance, d = 2, 3, and 5 for lines, circles, and ellipses, respectively. Our algorithm outputs all eligible curve components (a component is eligible if its size is at least a threshold k) in O(nd) time and linear space, where n is the number of points. Our only primitive operations are algebraic operations of bounded degrees and comparisons. We also propose an approximate algorithm with α-perfectness, which runs in (Formula presented) time and outputs (Formula presented) curves.
