Abstract

In this paper, the use of nonseparable wavelets for tomographic reconstruction is investigated. Local tomography is also presented. The algorithm computes both the quincunx approximation and detail coefficients of a function from its projections. Simulation results showed that nonseparable wavelets provide a reconstruction improvement versus separable wavelets.

摘要

本文研究了非可分离小波在层析重建中的应用。还介绍了局部层析成像。该算法从其投影中计算函数的 quincunx 逼近和细节系数。模拟结果表明，非可分离小波相对于可分离小波提供了重建改进。
