An approximation method for real images using quadratic curved surface units

摘要

The encompassing goal of our research is to propose an universal image model for real images. Based on that image signals can be described by a set of quadratic curved surface units, this paper presents a new image construction method using Laplacian pyramid. The experimental results shows that the signal of each Laplacian plane can be approximated successfully by a set of quadratic curved surface units, and it is clarified that any real image signals are represented by the simple mathematical function.
