Regional mapping of spekboom canopy cover using very high resolution aerial imagery
TL;DR: In this article, a per-pixel classification approach for canopy cover mapping of spekboom using multispectral 0.5m resolution aerial imagery is presented, where feature selection procedure that is robust to redundancy is applied in order to select an informative feature subset from a typical set of spectral, textural, and vegetation index features.

Spectral Similarity Assessment Based on a Spectrum Reflectance-Absorption Index and Simplified Curve Patterns for Hyperspectral Remote Sensing
TL;DR: A novel hyperspectral image similarity assessment index based on spectral curve patterns and a reflection-absorption index that can achieve higher precision and fewer points than the traditional spectral information divergence and spectral angle match.

How up-scaling of remote-sensing images affects land-cover classification by comparison with multiscale satellite images
TL;DR: The results indicate that the effects of resolution cannot be ignored and that resampling data may not be adequate for multi-spatial-scale classification compared with the native satellite images, and it is thus urgent to obtain an effective up-scaling algorithm that sharply reduces the problems caused by spatial heterogeneity.

Mapping Succession in Non-Forest Habitats by Means of Remote Sensing: Is the Data Acquisition Time Critical for Species Discrimination?
Katarzyna Osińska-Skotak,Aleksandra Radecka,Hubert Piórkowski,Dorota Michalska-Hejduk,Dominik Kopeć,Barbara Tokarska-Guzik,W. Ostrowski,Adam Kania,Jan Niedzielko +8 more
TL;DR: The results show that the time of remote sensing data acquisition influences the possibility of differentiating succession species, and the final recommendation for the data acquisition time should take into consideration the phenological cycle of deciduous species present within the research area and the abiotic conditions.

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.
