摘要

本文提出了一种快速的非均匀图像重建算法。提出了一种多分辨率方法，通过一组不规则间隔的样本来计算C/sup 2/-连续曲面。该算法利用从粗到精的控制格层次来生成一系列曲面，这些曲面的和接近所需的插值曲面。实验结果表明，从一组稀疏和不规则的样本中可以实现高保真的重建。

Nonuniform image reconstruction using multilevel surface interpolation

This paper describes a fast algorithm for nonuniform image reconstruction. A multiresolution approach is formulated to compute a C/sup 2/-continuous surface through a set of irregularly spaced samples. The algorithm makes use of a coarse-to-fine hierarchy of control lattices to generate a sequence of surfaces whose sum approaches the desired interpolating surface. Experimental results demonstrate that high fidelity reconstruction is possible from a selected set of sparse and irregular samples.
