Remote phenology: Applying machine learning to detect phenological patterns in a cerrado savanna
(2012 IEEE 8th International Conference on E-Science, e-Science 2012, 2012-12-01) [Trabalho apresentado em evento]
Plant phenology has gained importance in the context of global change research, stimulating the development of new technologies for phenological observation. Digital cameras have been successfully used as multi-channel ...
Anther, ovule and embryological characters in velloziaceae in relation to the systematics of pandanales
(Early Events In Monocot Evolution, 2013-01-01) [Trabalho apresentado em evento]
The movement of involucral bracts of Syngonanthus elegans (Eriocaulaceae-Poales): Anatomical and ecological aspects
(Flora, 2009-01-01) [Trabalho apresentado em evento]
Syngonanthus elegans flowers are distributed in capitula whose involucral bracts open and close in a diurnal rhythm. The anatomy of these bracts was studied to understand how such movements occur and how it influences ...
Evaluation of time series distance functions in the task of detecting remote phenology patterns
(Proceedings - International Conference on Pattern Recognition, 2014-01-01) [Trabalho apresentado em evento]
Phenology is the study of periodic natural phenomena and their relationship to climate. Usually, phenology studies consider the identification of patterns on temporal data. In those studies, several phenological change ...
Towards vegetation species discrimination by using data-driven descriptors
(2016 9th Iapr Workshop On Pattern Recognition In Remote Sensing (prrs), 2016-01-01) [Trabalho apresentado em evento]
In this paper, we analyse the use of Convolutional Neural Networks (CNNs or ConvNets) to discriminate vegetation species with few labelled samples. To the best of our knowledge, this is the first work dedicated to the ...
Influence of root interaction in eucalyptus clones under two environmental conditions
(Agriculture And Climate Change - Adapting Crops To Increased Uncertainty (agri 2015), 2015-01-01) [Trabalho apresentado em evento]
The global climate changes likely will alters water availability to plants. This makes relevant to investigate how plants manage water use. Competition for limited resources is constant in plant life. Competition for water ...
Guidelines for evaluating mobile applications: A semiotic-informed approach
(Lecture Notes in Business Information Processing, 2015-01-01) [Trabalho apresentado em evento]
Portable devices have been experimented for data acquisition in different domains, e. g., logistics and census data acquisition. Nevertheless, their large-scale adoption depends on the development of effective applications ...
SEMANTIC SEGMENTATION OF VEGETATION IMAGES ACQUIRED BY UNMANNED AERIAL VEHICLES USING AN ENSEMBLE OF CONVNETS
(2017 Ieee International Geoscience And Remote Sensing Symposium (igarss), 2017-01-01) [Trabalho apresentado em evento]
Vegetation segmentation in high resolution images acquired by unmanned aerial vehicles (UAVs) is a challenging task that requires methods capable of learning high-level features while dealing with fine-grained data. In ...
A semiotic-informed approach to interface guidelines for mobile applications: A case study on phenology data acquisition
(ICEIS 2015 - 17th International Conference on Enterprise Information Systems, Proceedings, 2015-01-01) [Trabalho apresentado em evento]
Portable devices have been experimented for data acquisition in different domains, e.g., logistics and census data acquisition. Nevertheless, their large-scale adoption depends on the development of effective applications ...
Phenological event detection by visual rhythms dissimilarity analysis
(Proceedings - 2014 IEEE 10th International Conference on eScience, eScience 2014, 2014-01-01) [Trabalho apresentado em evento]
Plant phenology has been exploited as an important research venue for assessing the impact of climate changes. One common approach for monitoring vegetation relies on the use of digital cameras. The employment of imaging ...
