Human action recognition in videos based on spatiotemporal features and bag-of-poses
(2020-10-01)
Currently, there is a large number of methods that use 2D poses to represent and recognize human action in videos. Most of these methods use information computed from raw 2D poses based on the straight line segments that ...
An integrated model for textual social media data with spatio-temporal dimensions
(Elsevier, 2020)
GPS-enabled devices and social media popularity have created an unprecedented opportunity for researchers to collect, explore, and analyze text data with fine-grained spatial and temporal metadata. In this sense, text, ...
Does the spatiotemporal distribution of tweets match the spatiotemporal distribution of flood phenomena? A study about the River Elbe Flood in June 2013
(The Pennsylvania State UniversityUniversity ParkPennsylvania, 2014-05-18)
In this paper we present a new approach to enhance information extraction from social media that relies upon
the geographical relations between twitter data and flood phenomena. We use specific geographical features like ...
Human action recognition using 2D poses
(2019-10-01)
The advances in video capture, storage and sharing technologies have caused a high demand in techniques for automatic recognition of humans actions. Among the main applications, we can highlight surveillance in public ...
Spatial spillovers in the implicit market price of soil erosion: an estimation using a spatio-temporal hedonic model
(Universidad de Montevideo, Facultad de Ciencias Empresariales y Economía, Departamento de Economía, 2019)
We estimate the implicit market price of soil erosion, fitting a spatio-temporal hedonic price model using quarterly data of 3,563 agricultural farms traded in Uruguay between 2000 and 2014. A unique feature of our estimation ...
Modulating factors of the abundance and distribution of Achelous spinimanus (Latreille, 1819) (Decapoda, Portunoidea), a fishery resource, in Southeastern Brazil
(2018-01-01)
This is the first study to examine how different environmental factors may influence the distribution of swimming crab Achelous spinimanus across geographically distant and distinct habitats. We analyzed the influence of ...
Human action recognition based on spatiotemporal features from videos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2020-12-22)
Currently, there is a high demand for the development of new techniques for automatic pattern recognition in videos, for example for the automatic recognition of human actions, this demand is motivated by the advances in ...
Automated analysis of leukocyte recruitment for in vivo studies using a spatiotemporal approach and multiple image features
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2020-03-30)
Over the last few years, many researchers have directed their efforts and interests toward in vivo studies of the cellular and molecular mechanisms in the microcirculation of many tissues under different inflammatory ...
