Chagas disease study using satellite image processing: A Bolivian case
(Elsevier Ltd, 2018-03)
Remote sensing is the technology that has enabled us to obtain information about the Earth's surface without directly contacting it. For this reason, currently, the Bolivian state has considered a list of interesting ...
Temporal analysis of the reduction in gas emission in areas of mechanically-harvested sugarcane using satellite imagery
(Pontificia Univ Catolica Chile, Fac Agronomia Ingenieria Forestal, 2010-01-01)
The primary objective of this study was to estimate the amount of gas not emitted into the air in areas cultivated with sugarcane (Saccharum officinarum) that were mechanically harvested. Satellite images CBERS-2/CCD, from ...
Morphological characterization of ponds and tidal courses in coastal wetlands using Google Earth imagery

QuMinS: fast and scalable querying, mining and summarizing multi-modal databases
(ElsevierNew York, 2014-04-20)
Given a large image set, in which very few images have labels, how to guess labels for the remaining majority? How to spot images that need brand new labels different from the predefined ones? How to summarize these data ...
Automatic object extraction from high resolution aerial imagery with simple linear iterative clustering and convolutional neural networks
(2019-09-17)
Recent advances in machine learning techniques for image classification have led to the development of robust approaches to both object detection and extraction. Traditional CNN architectures, such as LeNet, AlexNet and ...
3D Road extraction using a stereo pair of aerial images
(2010-01-01)
Road extraction from aerial and satellite imagery is of fundamental importance in the context of spatial data capturing and updating for GIS (Geographic Information System) applications. This article proposes a semiautomatic ...
