Support vector machines in remote sensing: A review

G Mountrakis, J Im, C Ogole - ISPRS journal of photogrammetry and remote …, 2011 - Elsevier
A wide range of methods for analysis of airborne- and satellite-derived imagery continues to
be proposed and assessed. In this paper, we review remote sensing implementations of …

Machine learning approaches to coastal water quality monitoring using GOCI satellite data

YH Kim, J Im, HK Ha, JK Choi, S Ha - GIScience & Remote …, 2014 - Taylor & Francis
Since coastal waters are one of the most vulnerable marine systems to environmental pollution,
it is very important to operationally monitor coastal water quality. This study attempts to …

Monitoring agricultural drought for arid and humid regions using multi-sensor remote sensing data

J Rhee, J Im, GJ Carbone - Remote Sensing of environment, 2010 - Elsevier
While existing remote sensing-based drought indices have characterized drought conditions
in arid regions successfully, their use in humid regions is limited. We propose a new remote …

Object‐based change detection using correlation image analysis and image segmentation

J Im, JR Jensen, JA Tullis - International journal of remote sensing, 2008 - Taylor & Francis
This study introduces change detection based on object/neighbourhood correlation image
analysis and image segmentation techniques. The correlation image analysis is based on the …

A change detection model based on neighborhood correlation image analysis and decision tree classification

J Im, JR Jensen - Remote Sensing of Environment, 2005 - Elsevier
This study introduces a change detection model based on Neighborhood Correlation Image
(NCI) logic. It is based on the fact that the same geographic area (eg, a 3×3 pixel window) …

Forest biomass estimation from airborne LiDAR data using machine learning approaches

CJ Gleason, J Im - Remote Sensing of Environment, 2012 - Elsevier
During the past decade, procedures for forest biomass quantification from light detection
and ranging (LiDAR) data have been improved at a rapid pace. The scope of these methods …

Synergistic use of QuickBird multispectral imagery and LIDAR data for object-based forest species classification

Y Ke, LJ Quackenbush, J Im - Remote Sensing of Environment, 2010 - Elsevier
This study evaluated the synergistic use of high spatial resolution multispectral imagery (ie,
QuickBird, 2.4m) and low-posting-density LIDAR data (3m) for forest species classification …

Comparative assessment of various machine learning‐based bias correction methods for numerical weather prediction model forecasts of extreme air temperatures in …

D Cho, C Yoo, J Im, DH Cha - Earth and Space Science, 2020 - Wiley Online Library
Forecasts of maximum and minimum air temperatures are essential to mitigate the damage
of extreme weather events such as heat waves and tropical nights. The Numerical Weather …

Estimating ground-level particulate matter concentrations using satellite-based data: a review

M Shin, Y Kang, S Park, J Im, C Yoo… - GIScience & Remote …, 2020 - Taylor & Francis
Particulate matter (PM) is a widely used indicator of air quality. Satellite-derived aerosol
products such as aerosol optical depth (AOD) have been a useful source of data for ground-level …

Characteristics of Landsat 8 OLI-derived NDVI by comparison with multiple satellite sensors and in-situ observations

Y Ke, J Im, J Lee, H Gong, Y Ryu - Remote sensing of environment, 2015 - Elsevier
Vegetation indices are important remotely sensed metrics for ecosystem monitoring and
land surface process assessment, among which Normalized Difference Vegetation Index (NDVI) …
