3D hyperspectral point cloud generation: Fusing airborne laser scanning and hyperspectral imaging sensors for improved object-based information extraction
TL;DR: It is shown that the complementary implementation of spectral and 3D information at the point-cloud scale improves object-based classification and information extraction schemes and has great potential for numerous land-cover mapping and environmental applications.

Hyperspectral Image Classification Using Spectral–Spatial Composite Kernels Discriminant Analysis
Hong Li,Zhijing Ye,Guangrun Xiao +2 more
TL;DR: Experimental results show that the spatial information extracted by GWLM can greatly improve the performance, and demonstrate the superiority of CKDA for HSI classification in the case of few labeled samples.

Size of sampling unit strongly influences detection of seedling limitation in a wet tropical forest.
TL;DR: For more common species, much lower estimates of seedlings limitation at mature crown scales suggest weaker influence of seedling limitation on community dynamics than previously assumed.

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.

TL;DR: Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
