Abstract:
|
The Laplacian Pyramid is a new and efficient method for image encoding. The method is of increasing interest as band-pass pyramids and multiresolution images are being used in other image processing applications. The Pyramid Coding system is a hierarchical structure well suited for progressive image transmission over low-speed channels and hierarchical image retrieving in com- puterized image storage. The goal if this paper is to present a new pyramidal image structure that uses algorithms defined on arbitrary non-rectangular 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. |
