Generating virtual images from oblique frames
Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...
Efficient parallelization on GPU of an image smoothing method based on a variational model
Medical imaging is fundamental for improvements in diagnostic accuracy. However, noise frequently corrupts the images acquired, and this can lead to erroneous diagnoses. Fortunately, image preprocessing algorithms can ...
Multiple imaging radiography at LNLS
(ELSEVIER SCIENCE BVAMSTERDAM, 2008)
An analyzer-based X-ray phase-contrast imaging (ABI) setup has been mounted at the Brazilian Synchrotron Light Laboratory (LNLS) for multiple imaging radiography (MIR) purposes. The algorithm employed for treating the MIR ...
Brain tissue MR-image segmentation via optimum-path forest clustering

Verifying the high-order consistency of training images with data for multiple-point geostatistics
Parameter inference is a key aspect of spatial modeling. A major appeal of variograms is that they allow inferring the spatial structure solely based on conditioning data. This is very convenient when the modeler does not ...

Links Between Image Segmentation Based on Optimum-Path Forest and Minimum Cut in Graph
A semi-automatic method for indirect orientation of aerial images using ground control lines extracted from airborne laser scanner data
This paper presents a method for indirect orientation of aerial images using ground control lines extracted from airborne Laser system (ALS) data. This data integration strategy has shown good potential in the automation ...
