Fractional-Level Processing of Multiresolution Images

An approach of displaying and editing multiresolution images at fractional levels is presented. Haar wavelet transformation has been used to create multiresolution images and represent them in discrete quadtree. To realize the smooth transition of such images between different levels, we first give an interpolation algorithm based on the integer-level zooming. Then we further work out a fractional-level zooming and editing algorithm. Some experimental results are given.
