The convolution back projection algorithm based on windows function

Abstract

In this paper, some efficient image reconstruction algorithms in industrial computed tomography with the fanbeam projection based on windows function was discussed in detail. In order to improve the quality of image reconstruction, windows functions of image reconstruction of convolution back projection was proposed. The windows functions method ameliorates the process of image reconstruction. The efficiency of windows function is evaluated in contrast to that of its traditional serial counterpart. Experiment results clearly demonstrate that windows function can efficiently improve quality of images reconstruction.Index Terms-windows function, convolution back projection, fan-beam scan mode, interpolation.

Image Reconstruction Enhancement Using Convolution Back Projection Method for Electrical Tomography Application

“…2. The convolution at a specific point or pixel is the product of the two functions as follows [9,10]. The CBP algorithm is employed on the LBP reconstructed tomographic images to reduce the problem with blurry edges and inaccurate size or shape of the subject of measurement.…”
