Abstract
A multi-level image data structure (called a multi-level image stack) containing a single image at each level and a method for generating the same. Images at each level contain the same number of pixels. The multi-level image stack defines a set of levels emanating from an original image having a number of pixels. Each successive level of the multi-level image stack contains a single image. Each single image contains the same number of pixels as the original image. Successive levels encode progressively filtered information of the original image, but without subsampling. This retains the fine-scale resolution of the original image. A variety of filter techniques can be used, including a Gaussian filter and a box filter. The multi-level image stack is particularly well-suited for use in texture synthesis applications, where its fine-scale resolution at all levels has the advantage of reducing artifacts and spatial quantization.
