3D measurements in conventional X-ray imaging with RGB-D sensors

Albiol Colomer, Francisco; Corbi, Alberto; Albiol Colomer, Alberto (Elsevier, 2017-04)

[EN] A method for deriving 3D internal information in conventional X-ray settings is presented. It is based on the combination of a pair of radiographs from a patient and it avoids the use of X-ray-opaque fiducials and ...
A portable geometry-independent tomographic system for gamma-ray, a next generation of nuclear waste characterization

Tortajada, Salvador; Albiol, Francisco; Caballero, Luis; Albiol Colomer, Alberto; Leganés-Nieto, Jose Luis (Nature Publishing Group, 2023-07-28)

[EN] One of the main activities of the nuclear industry is the characterisation of radioactive waste based on the detection of gamma radiation. Large volumes of radioactive waste are classified according to their average ...
Automatic intensity windowing of mammographic images based on a perceptual metric

Albiol Colomer, Alberto; Corbi, Alberto; Albiol Colomer, Francisco (John Wiley & Sons, 2017-04)

[EN] Purpose: Initial auto-adjustment of the window level WL and width WW applied to mammographic images. The proposed intensity windowing (IW) method is based on the maximization of the mutual information (MI) between a ...
Evaluation of modern camera calibration techniques for conventional diagnostic X-ray imaging settings

Albiol Colomer, Francisco; Corbi, Alberto; Albiol Colomer, Alberto (Springer-Verlag, 2017-03)

[EN] We explore three different alternatives for obtaining intrinsic and extrinsic parameters in conventional diagnostic X-ray frameworks: the direct linear transform (DLT), the Zhang method, and the Tsai approach. We ...
Geometrical Calibration of X-Ray Imaging With RGB Cameras for 3D Reconstruction

Albiol Colomer, Francisco; Corbi, Alberto; Albiol Colomer, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2016-08)

We present a methodology to recover the geometrical calibration of conventional X-ray settings with the help of an ordinary video camera and visible fiducials that are present in the scene. After calibration, equivalent ...
Indexación de imágenes de eventos deportivos

Ríos Benet, David (Universitat Politècnica de València, 2017-03-10)

Este TFG implementa un algoritmo capaz de detectar y procesar el o los dorsales presentes en una o varias imágenes a analizar mediante el uso de técnicas de procesado y tratamiento de imágenes. Este resultado es posteriormente ...
