SPECTRAL-SPATIAL CLASSIFICATION OF HYPERSPECTRAL REMOTE SENSING IMAGES USING VARIATIONAL AUTOENCODER AND CONVOLUTION NEURAL NETWORK
Hyperspectral classification feature extraction spectral channels deep learning
2019/2/28
In this paper, we propose a spectral-spatial feature extraction framework based on deep learning (DL) for hyperspectral image (HSI) classification. In this framework, the variational autoencoder (VAE)...

Spatial distribution of 87Sr/86Sr ratios of stream sediments in Shikoku Island and the Kii Peninsula, Southwest Japan
geochemical map stream sediment
2017/4/11
Geochemical mapping of 87Sr/86Sr ratios in Shikoku Island and the Kii Peninsula of Southwest Japan was performed
using 233 samples of stream sediments (<180 μm). The spatial distribution of 87Sr/86Sr...
Using hilltop curvature to derive the spatial distribution of erosion rates
Using hilltop curvature derive the spatial distribution erosion rates
2014/5/20
Erosion rates dictate the morphology of landscapes, and therefore quantifying them is a critical part of many geomorphic studies. Methods to directly measure erosion rates are expensive and time consu...

2017/4/11
A total of 74 surface and subsurface water samples at depths shallower than 200 m were collected in the eastern East
China Sea (ECS), and spatial and seasonal variations in 226Ra, 228Ra, and 228Th ac...
The role of mineral surfaces in the preservation and transformation of organic carbon: meso- to nano– scale spatial complexity of organic matter forms in organic-rich shales
mineral surfaces preservation transformation organic carbon meso- to nano– scale spatial complexity organic matter forms organic-rich shales
2012/3/30
Sequestration of organic matter (OM) in sediments is a fundamental biogeochemical process that regulates planetary temperature, the flux of free oxygen to the atmosphere and oceans, and the distributi...
