Spatial Resolution Analysis for Few-Views Discrete Tomography Based on MART-AP Algorithm

On double-resolution imaging in discrete tomography

Super-resolution imaging aims at improving the resolution of an image by enhancing it with other images or data that might have been acquired using different imaging techniques or modalities. In this paper we consider the task of doubling the resolution of tomographic grayscale images of binary objects by fusion with double-resolution tomographic data that has been acquired from two viewing ang...

Analysis on the strip-based projection model for discrete tomography

Discrete tomography deals with image reconstruction of an object with finitely many gray levels (such as two). Different approaches are used to model the raw detector reading. The most popular models are line projection with a lattice of points and strip projection with a lattice of pixels/cells. The line-based projection model fits some applications but involves a major approximation since the...

Discrete tomography based on a modified SIRT algorithm

Filtered Back Projection and Simultaneous Iterative Reconstruction Technique (SIRT) are the most popular reconstruction algorithms in electron tomography. In both cases every TEM image is smeared back into object space along the original pathway (so-called back-projection). Both methods produce a blurring of the reconstructed objects, which affects the segmentation step after reconstruction. Fo...
