Remote sensing of boreal forest biophysical and inventory parameters: a review
TL;DR: In this paper, the authors reviewed the literature on the remote sensing of boreal forests in order to determine if common frameworks for monitoring and assessing change in forest biophysical and inventory parameters could be developed.
Journal ArticleDOI
Estimation of the stand ages of tropical secondary forests after shifting cultivation based on the combination of WorldView-2 and time-series Landsat images
TL;DR: In this article, a new method to estimate stand ages of secondary vegetation in the Bornean montane zone was developed, where local people conduct traditional shifting cultivation and protected areas are surrounded by patches of recovering secondary vegetation of various ages.

Intraspecific Differences in Spectral Reflectance Curves as Indicators of Reduced Vitality in High-Arctic Plants
Bogdan Zagajewski,Hans Tømmervik,Jarle W. Bjerke,Edwin Raczko,Zbigniew Bochenek,Andrzej Kłos,Anna Jarocińska,Samantha Lavender,Dariusz Ziółkowski +8 more
TL;DR: Two key arctic tundra species, Cassiope tetragona and Dryas octopetala, exhibited significant differences in this spectral region that were linked to a changing health status, indicating that species-specific changes due to environmental conditions can be differentiated in the 1401–2400 nm spectral region.

Pattern classification and scene analysis
Richard O. Duda,Peter E. Hart +1 more
TL;DR: In this article, a unified, comprehensive and up-to-date treatment of both statistical and descriptive methods for pattern recognition is provided, including Bayesian decision theory, supervised and unsupervised learning, nonparametric techniques, discriminant analysis, clustering, preprosessing of pictorial data, spatial filtering, shape description techniques, perspective transformations, projective invariants, linguistic procedures, and artificial intelligence techniques for scene analysis.

A new method for non-parametric multivariate analysis of variance
TL;DR: In this article, a non-parametric method for multivariate analysis of variance, based on sums of squared distances, is proposed. But it is not suitable for most ecological multivariate data sets.
