Abstract (Summary of the Work)

This report present a simple algorithm for the matching of line segments in2D under similarity transformations. Given a set S of m line segments, called sample set, and a pattern set P of k line segments (k ≤ m), the problem is to find a matching of P with a subsct of S under similarity transformations. The proposed algorithm requires O(n) space and preprocessing time O(n log(n)), and worst case query time complexity is O(kn log(n) + n2). If set S consists of non parallel line segments then time complexity for such a case will reduce to O(kn log(n))
