Semi-Supervised Hyperspectral Image Classification Based on Label Propagation via Selected Path

IEEE Access, 2020
Most graph-based semi-supervised classification methods do not perform well in hyperspectral image classification tasks due to their high complexity and other limitations.

Approximation hardness of dominating set problems in bounded degree graphs [PDF]

, 2008
We study approximation hardness of the Minimum Dominating Set problem and its variants in undirected and directed graphs. Using a similar result obtained by Trevisan for Minimum Set Cover we prove the first explicit approximation lower bounds for various

Development of FT-NIR Models for the Simultaneous Estimation of Chlorophyll and Nitrogen Content in Fresh Apple (Malus Domestica) Leaves

Sensors, 2015
Agricultural practices determine the level of food production and, to great extent, the state of the global environment. During the last decades, the indiscriminate recourse to fertilizers as well as the nitrogen losses from land application have been ...

Genetic diversity and divergence at the Arbutus unedo L. (Ericaceae) westernmost distribution limit.

PLoS ONE, 2017
Mediterranean forests are fragile ecosystems vulnerable to recent global warming and reduction of precipitation, and a long-term negative effect is expected on vegetation with increasing drought and in areas burnt by fires.

Multi-branch Deep Learning Architecture for bathymetric LiDAR Point Cloud Classification [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Accurate classification of topo-bathymetric LiDAR data remains challenging due to the heterogeneous nature of land-water transitional environments, where terrestrial, water surface, and submerged features must be distinguished simultaneously.

Spanning trees with generalized degree constraints arising in the design of wireless networks [PDF]

, 2011
In this paper we describe a minimum spanning tree problem with generalized degree constraints which arises in the design of wireless networks. The signal strength on the receiver side of a wireless link decreases with the distance between transmitter and
