Severe forest disturbance events are becoming more common due to climate change and many forest managers rely heavily upon airborne surveys to map damage. However, when the damage is extensive, airbor...
UNSUPERVISED CLASSIFICATION OF POLARIMETRIC SAR DATA USING IMAGE CLUSTERING AND H/A/α DECOMPOSITION
Image Classification Data Clustering H/A/a Polarimetric SAR Iteration POLSARPRO
2016/3/17
This paper proposed a method of unsupervised classification of polarimetric SAR data based on image clustering and H/A/a decomposition. Fully polarimetric L band data collected by ALOS PALSAR system w...
GENETIC ALGORITHMS FOR THE UNSUPERVISED CLASSIFICATION OF SATELLITE IMAGES
Remote Sensing Analysis Unsupervised Classification Genetic Algorithm Davies-Bouldin's Index Heuristic Algorithm ISODATA

ESTIMATING LANDSCAPE PATTERN FROM SUPERVISED AND UNSUPERVISED CLASSIFICATION:STUDIES IN THE WESTERN GHATS,INDIA
Accuracy Classification Ecosystems Interpretation Land use/Land cover Pattern recognition Spatial data Sustainability
2015/2/4
Current research suggests that metrics of landscape pattern can act as indicators of ecological processes and biodiversity
maintenance. Land cover maps, created through remote sensing, enable the eva...
Variational Bayes approach for model aggregation in unsupervised classification with Markovian dependency
Model averaging Variational Bayes inference Markov Chain Unsu-pervised classification
2011/6/16
We consider a binary unsupervised classi cation problem where each observation
is associated with an unobserved label that we want to retrieve. More precisely, we
assume that there are two groups of...
Unsupervised classification of saturated areas using a time series of remotely sensed images
hydrologically active areas Normalized Difference Water Index
2009/5/13
The spatial distribution of saturated areas is an important consideration in numerous applications, such as water resource planning or siting of management practices. However, in humid well vegetated ...
