Abstract :
A pyramidal image structure is presented that uses algorithms defined on arbitrary nonrectangular sampling lattices. An adaptive technique is also developed that assigns to the pyramidal structure an optimum sampling lattice as a function of the frequency content of the original image. Two algorithms, one in the frequency domain and the other in the spatial domain are used to select the optimum sampling lattice
