Journal ArticleDOI
Mapping tree species in tropical seasonal semi-deciduous forests with hyperspectral and multispectral data
Matheus Pinheiro Ferreira,Maciel Zortea,Daniel Capella Zanotta,Yosio Edemir Shimabukuro,Carlos Roberto de Souza Filho +4 more
TL;DR: In this article, three supervised machine learning classifiers were applied to discriminate the species at the pixel level, and linear discriminant analysis outperformed Support Vector Machines with Linear and Radial Basis Function (RBF-SVMs) kernels and Random Forests in almost all the tested cases.
Journal ArticleDOI
Using the U-net convolutional network to map forest types and disturbance in the Atlantic rainforest with very high resolution images
Fabien Wagner,Alber Sanchez,Yuliya Tarabalka,Rodolfo G. Lotte,Matheus Pinheiro Ferreira,Matheus Pinheiro Ferreira,Marcos P. M. Aidar,Emanuel Gloor,Oliver L. Phillips,Luiz E. O. C. Aragão,Luiz E. O. C. Aragão +10 more
TL;DR: In this article, a U-net convolutional network was used to identify and segment natural forests and eucalyptus plantations, and an indicator of forest disturbance, the tree species Cecropia hololeuca, in very high resolution images (0.3 m) from the WorldView-3 satellite in the Brazilian Atlantic rainforest region.
Journal ArticleDOI
Tree species classification in tropical forests using visible to shortwave infrared WorldView-3 images and texture analysis
Matheus Pinheiro Ferreira,Matheus Pinheiro Ferreira,Fabien Wagner,Luiz E. O. C. Aragão,Luiz E. O. C. Aragão,Yosio Edemir Shimabukuro,Carlos Roberto de Souza Filho +6 more
TL;DR: In this paper, the authors performed a comprehensive assessment of WorldView-3 images acquired in the dry and wet seasons for tree species discrimination in tropical semi-deciduous forests, and applied an individual tree crown (ITC)-based approach that employed pan-sharpened VNIR bands and gray level co-occurrence matrix texture features.
Journal ArticleDOI
Individual tree crown delineation in a highly diverse tropical forest using very high resolution satellite images
Fabien Wagner,Matheus Pinheiro Ferreira,Matheus Pinheiro Ferreira,Alber Sanchez,Mayumi C. M. Hirye,Maciel Zortea,Emanuel Gloor,Oliver L. Phillips,Carlos Roberto de Souza Filho,Yosio Edemir Shimabukuro,Luiz E. O. C. Aragão,Luiz E. O. C. Aragão +11 more
TL;DR: In this article, a method of automatic tree crown delineation based only on very high resolution images from WorldView-2 satellite and apply it to a region of the Atlantic rain forest with highly heterogeneous tropical canopy cover is presented.
Journal ArticleDOI
Individual tree detection and species classification of Amazonian palms using UAV images and deep learning
Matheus Pinheiro Ferreira,Danilo Roberti Alves de Almeida,Daniel de Almeida Papa,Juliano Baldez Silva Minervino,Hudson Franklin Pessoa Veras,Arthur Formighieri,Caio Alexandre Nascimento Santos,Marcio Aurélio Dantas Ferreira,Evandro Orfanó Figueiredo,Evandro José Linhares Ferreira +9 more
TL;DR: In this article, the authors developed a method to map Amazonian palm species at the individual tree crown (ITC) level using RGB images acquired by a low-cost unmanned aerial vehicle (UAV).
