Unsupervised Change Detection Driven by Floating References: A Pattern Analysis Approach
(2021-01-01)
The Earth’s environment is continually changing due to both human and natural factors. Timely identification of the location and kind of change is of paramount importance in several areas of application. Because of that, ...
Proposal of a new stability concept to detect changes in unsupervised data streams
(Pergamon-ElsevierOxford, 2014-11-15)
Learning from continuous streams of data has been receiving an increasingly attention in the last years. Among the many challenges related to mining data streams, change detection is one topic frequently addressed. Being ...
Spectral-Spatial-Aware Unsupervised Change Detection with Stochastic Distances and Support Vector Machines
(2021-04-01)
Change detection is a topic of great interest in remote sensing. A good similarity metric to compute the variations among the images is the key to high-quality change detection. However, most existing approaches rely on ...
Analyzing Spatio-temporal Land Cover Dynamics in an Atlantic Forest Portion Using Unsupervised Change Detection Techniques
(2021-01-01)
Over the past decades, the Southeast Atlantic Forest in Paraíba do Sul River Valley has suffered intense deforestation and human disturbances. Due to the Atlantic Forest biodiversity and the economic relevance of such a ...
Unsupervised density-based behavior change detection in data streams
(IOS PressAmsterdam, 2014)
The ability to detect changes in the data distribution is an important issue in Data Stream mining. Detecting changes in data distribution allows the adaptation of a previously learned model to accommodate the most recent ...
Analysis of change detection techniques for disaster mapping using remote sensing dataAnálise de técnicas de detecção de mudança para mapeamento de desastres com uso de dados de sensoriamento remoto
(2020-03-01)
In recent years Brazil has suffered a series of environmental disasters that impaired its society, economy, and biodiversity in immeasurable levels. The use of remote sensing data rises as a fundamental source when analyzing ...
