Abstract

We have developed a new image display and editing system. A conventional multiresofotion wavelet analysis can only operate on the image of the integer level resolutions. Since the resolution of the in­ teger levels are discrete, a conventional image display and editing system using Haar wavelet only pro­ vides for discrete levels of zooming in which the resolution doubles at each level. This system extends conventional multiresolution wavelet analysis to non-integer level resolutions. The transformation to the non -integer level resolution makes it possible to operate on images with resolution between the in­ teger levels. By using this system users can manipulate images at a desired level of resolutions, while preserving the storage requirement as much as that of a conventional system. This non-integer level analysis can be applied to a wide variety of applications.
