摘要

本文提出了一种基于自适应和小波相结合的三维图像重建系统，并利用b小波函数进行插值。结果表明，该系统可用于三维图像重建，也可对巴西农业研究企业(EMBRAPA农业仪器)开发的用于土壤科学的X和/spl伽马/射线计算机微型断层扫描仪获得的数据进行插值。此外，对于二维图像，与过滤后的反投影方法相比，对于一组特定的幻影图像，观察到一些优势。本系统是在Windows环境下用Pascal和C/ c++语言开发的。

Three-dimensional reconstruction and visualization of tomographic images system using frequential techniques and wavelets

This paper presents a system for three-dimensional image reconstruction based on the combination of both adaptive and wavelet reconstruction methods and the use of B-wavelets function for interpolation. Results show the usefulness of the system for three-dimensional image reconstruction and also after interpolation with data obtained by X and /spl gamma/-ray computerized minitomograph scanners for soil science developed at the Brazilian Enterprise for Agricultural Research (EMBRAPA Agricultural Instrumentation). Also for two-dimensional images some advantages were observed when compared with the filtered backprojection method for a particular set of phantom images. The system was developed in Pascal and C/C++ languages under a Windows environment.
