反投影

• In this paper , firstly , we studied the newly working in the field of the application of wavelets transform used - in the computer tomography in two - dimesion , and mainly focused in the field of filter - backprojection algorithm . we analized the application of one - demision wavelets transform and two - demision wavlets transform
  本文首先对小波理论在二维图像重建应用的最新研究进行分析，着重研究了了小波理论在滤波反投影算法中的具体算法，分别从一维小波变换和二维小波变换进行了探讨。
