Resolution (digital) pyramids can be used to simulate the effect produced on the shape of a pattem by a modification of the observation distance in the real world. Binary OR- and AND-pyramids are easy to build, but distort the shape significantly. Here a grey level pyramid is built, which produces significantly better results.

Abstract
Resolution (digital) pyramids can be used to simulate the effect produced on the shape of a pattem by a modification of the observation distance in the real world. Binary OR- and AND-pyramids are easy to build, but distort the shape significantly. Here a grey level pyramid is built, which produces significantly better results.File in questo prodotto:
