摘要

本文提出一种不需要模型引导的方法

从两个一维正交投影重建二维图象。利用树搜索原理

将问题树的层和分支与图象的行、列变换对应

建立一个有记忆能力的数据结构

通过启发式搜索完成图象重建。这种方法解决了文献[3]中存在的不足。实验证明了本文方法的有效性。

Abstract

A reconstruction methods is presented

by which the 2-D image can be reconstructed from

their two orthogonal projections without models. Based on the strategy of the tree-search

the levels and branchs of the problem-tree are corresponding to the row and column transforms in the 2-D image

respectively

and a memorable data structure is introduced. So

the image can be reconstructed after heuristic searches. This method solves some drawbacks in the reference[3]. The experiments show the usefulness of this methods.
