National-scale soybean mapping and area estimation in the United States using medium resolution satellite imagery and field survey
(2017)
Reliable and timely information on agricultural production is essential for ensuring world food security. Freely available medium-resolution satellite data (e.g. Landsat, Sentinel) offer the possibility of improved global ...
Multithresholding techniques in SAR image classification
(Elsevier Science, 2021-08)
Beyond bilevel segmentation, multithresholding (MT) is a powerful technique that is seldom considered in image analysis. In active imaging techniques, however, MT appears as a significant alternative due to its obliviousness ...
Assessment of surface water at the Sobradinho reservoir under the effects of drought using multi-temporal Landsat Images
(2016-01-01)
The matrix of energy generation in Brazil is predominantly hydroelectric power. Consequently, the reservoirs need constant monitoring due to the large volume of artificially dammed water. Images from remote sensing can ...
