Abstract
The most efficient currently known algorithms for two dimensional matching with rotation have a worst case time complexity of O(n 2 m 3), where the size of the text is n 2 and the size of the pattern is m 2. In this paper we present two algorithms for the two dimensional rotated matching problem whose running time is O(n 2 m 2). The preprocessing time of the first algorithms is O(m 5) and the preprocessing time of the second algorithm is O(m 4).
