Abstract :
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 γ-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
