Angle-by-Angle Reconstruction of Three-Dimensional Volumetric Information Using Computational Integral Imaging

Digital Holography and Three-Dimensional Imaging, 2011
A computational reconstruction technique with variable viewing angles is proposed, which simulates non-parallel reconstuction planes. Experimental results support the validity that the image is reconstructed only at the exact angular position.

An Algorithm for Fast Computation of 3D Krawtchouk Moments for Volumetric Image Reconstruction

, 2016
Discrete Krawtchouk moments are powerful tools in the field of image processing application and pattern recognition. In this paper we propose an efficient method based on matrix multiplication and symmetry property to compute 3D Krawtchouk moments. This new method is used to reduce the complexity and computational time for 3D object reconstruction. The

Computational integral-imaging reconstruction-based 3-D volumetric target object recognition by using a 3-D reference object

Applied Optics, 2009
In this paper, we propose a novel computational integral-imaging reconstruction (CIIR)-based three-dimensional (3-D) image correlator system for the recognition of 3-D volumetric objects by employing a 3-D reference object. That is, a number of plane object images (POIs) computationally reconstructed from the 3-D reference object are used for the 3-D ...

Volumetric reconstruction and stereotactic computer assisted resection in intracerebral lesions

Acta Neurochirurgica, 1996
Since 1990 112 patients have undergone stereotactic resection of intra-axial tumoural lesions with volumetric reconstruction, using the Kelly-Goerss system. Stereotactic integration of CT, angiographic and particularly MRI information, together with three-dimensional information of the lesion, provide an innovative evaluation of the most appropriate ...

High‐Quality Volumetric Reconstruction on Optimal Lattices for Computed Tomography

Computer Graphics Forum, 2009
AbstractWithin the context of emission tomography, we study volumetric reconstruction methods based on the Expectation Maximization (EM) algorithm. We show, for the first time, the equivalence of the standard implementation of the EM‐based reconstruction with an implementation based on hardware‐accelerated volume rendering for nearest‐neighbor (NN ...
