The use of area-maximising points (AMPs) is proposed as a method for improving the performance of window query processing. The AMP method is a progressive approximation method and is used to identify hits from the candidates. It involves the use of four sampled points of an object and shows a higher filter ratio and shorter processing time when compared with established approximation methods.
