An Efficient Approach for Change Detection in SAR Images
This paper presents an unsupervised distribution free change detection for Synthetic Aperture Radar (SAR) images based on an image fusion strategy and novel fuzzy clustering algorithm with a Markov Random Field (MRF). By finding the mean ratio and log ratio on the two original images the SWT based fusion rules is applied for performing image fusion. This image fusion technique is introduced to ...
متن کاملChange detection from synthetic aperture radar images based on neighborhood-based ratio and extreme learning machine
Change detection is of high practical value to hazard assessment, crop growth monitoring, and urban sprawl detection. A synthetic aperture radar (SAR) image is the ideal information source for performing change detection since it is independent of atmospheric and sunlight conditions. Existing SAR image change detection methods usually generate a difference image (DI) first and use clustering me...
متن کاملA change detection measure based on a likelihood ratio and statistical properties of SAR intensity images
With its weatherand illumination-independent characteristics, synthetic aperture radar (SAR) has become an important tool for change detection. There are two critical steps in SAR image change detection: designing a change detector and choosing a decision rule. Given a measure from a change detector, the change detection results could be sensitive to the decision rule, such as the selection of ...
متن کاملSurvey on Change Detection in SAR Images
Change detection in remote sensing images becomes more and more important for the last few decades, among them change detection in Synthetic Aperture Radar (SAR) images are having some more difficulties than optical ones due to the fact that SAR images suffer from the presence of the speckle noise. In this paper the Systematic survey of the common processing steps and core decision rules for ch...
