Um filtro gaussiano adaptativo para análise comparativa de imagens de radares e satélites meteorológicos
(2011-09-12)
Meteorological satellite and radar data comparative analysis allows to correlate the precipitation structures observed in both images. Such analysis would make feasible the extension of the range of ground-based meteorological ...
Video quality metric for streaming service using DASH standard

Improving elevation resolution in phased-array inspections for NDT
(Elsevier, 2019-01)
The Phased Array Ultrasonic Technique (PAUT) offers great advantages over the conventional ultrasound technique (UT), particularly because of beam focusing, beam steering and electronic scanning capabilities. However, the ...
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. ...
Fractal dimension of the mandibular trabecular bone measured on digital and digitized images.
(2015)
Aims: This study compared fractal dimension (FD) values on mandibular trabecular bone in digital and digitized images at different spatial and contrast resolutions. Materials and Methods: 12 radiographs of dried human ...
Road segment delineation using active testing principle and an edge-based post-processing strategy
(2003-12-01)
This paper presents a semi-automated method for extracting road segments from medium-resolution images based on active testing and edge analysis. The method is based on two sequential and independent stages. Firstly, an ...
