Hyperspectral and LiDAR Data Fusion: Outcome of the 2013 GRSS Data Fusion Contest

TL;DR: This paper highlights the two awarded research contributions, which investigated different approaches for the fusion of hyperspectral and LiDAR data, including a combined unsupervised and supervised classification scheme, and a graph-based method for the Fusion of spectral, spatial, and elevation information.
Journal ArticleDOI

Processing of Multiresolution Thermal Hyperspectral and Digital Color Data: Outcome of the 2014 IEEE GRSS Data Fusion Contest

TL;DR: The Contest was proposed as a double-track competition: one aiming at accurate landcover classification and the other seeking innovation in the fusion of thermal hyperspectral and color data, resulting in the results obtained by the winners of both tracks.
Journal ArticleDOI

Generalized Graph-Based Fusion of Hyperspectral and LiDAR Data Using Morphological Features

TL;DR: In this letter, a generalized graph-based fusion method to couple dimension reduction and feature fusion of the spectral information (of the original HSI and MPs) and MPs (built on both HS and LiDAR data) is proposed, where the edges of the fusion graph are weighted by the distance between the stacked feature points.
Journal ArticleDOI

Improved Classification of VHR Images of Urban Areas Using Directional Morphological Profiles

TL;DR: This paper introduces two improvements on the use of morphological profiles by using linear SEs and shows that the addition of the line-based MP gives a substantial improvement of the classification result.
Journal ArticleDOI

A review of urban air pollution monitoring and exposure assessment methods

TL;DR: A comprehensive review of the recent development in air pollution monitoring, including both the pollution data acquisition and the pollution assessment methods, and presents the efforts of applying these models on the mobile sensing data and discusses the future research of fusing the stationary and mobile sensingData.
