Toward reduction of artifacts in fused images
(2011)
Most fusion satellite image methodologies at pixel-level introduce false spatial details, i.e. artifacts, in the resulting fused images. In many cases, these artifacts appears because image fusion methods do not consider ...
A pan-chromatic view of the galaxy cluster XMMU J1230.3+1339 at z = 0.975. Observing the assembly of a massive system
(2011)
Context. Observations of the formation and evolution of massive galaxy clusters and their matter components provide crucial constraints on cosmic structure formation, the thermal history of the intracluster medium (ICM), ...
An alternative to updating topographic maps using SPOT images
(2000-01-01)
Brazil has serious problems in systematic mapping and cartographic updating. Only 13% of the country is mapped in scale 1:50,000 and most of these maps are from approximately 30 years ago. Usually, professionals such as ...
Accuracy improvements in the orientation of ALOS PRISM images using IOP estimation and UCL Kepler platform model
(2017-07-01)
This paper presents a study that was conducted to determine the orientation of ALOS (Advanced Land Observing Satellite) PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) triplet images, considering the ...
Análisis geomorfológico de la costa central sur de Chile en imagenes de Sky lab 3 experimento 190 A
(Universidad de Chile, 1977)
The material fron SKYLAB 190 A was examined in posirive transparences of1 1/4 x 2 1/4 in., which belong to 6 bands. 1: was observed the better bands that are those of 0.6 - 0.7 microns (panchromatic. hlack and white), 0.5 ...
Analysis of images in the discrimination of land cover, by processing radar satellite images
(Universidad Continental, 2019-10-02)
In the evaluation of terrestrial coverage by means of remote sensors, we find a variety of techniques dedicated to be able to register the terrestrial coverage, one of them is the use of optical satellite images also known ...
Shadow detection improvement using spectral indices and morphological operators in Urban Areas in high resolution images
(2015-01-01)
While high-resolution remote sensing images have increased application possibilities for urban studies, the large number of shadow areas has created challenges to processing and extracting information from these images. ...
