Targeted change detection in remote sensing images
Recent developments in the remote sensing systems and image processing made it possible to propose a new method of the object classification and detection of the specific changes in the series of satellite Earth images (so called targeted change detection). In this paper we propose a formal problem statement that allows to use effectively the deep learning approach to analyze time-dependent ser...
متن کاملCombining of Magnitude and Direction of Change Indices to Unsupervised Change Detection in Multitemporal Multispectral Remote Sensing Images
In remote sensing, image-based change detection techniques, analyze two images acquired over the same area at different times t1 and t2 to identify the changes occurred on the Earth's surface. Change detection approaches are mainly categorized as supervised and unsupervised. Generating the change index is a key step for change detection in multi-temporal remote sensing images. Unsupervised chan...
متن کاملUnsupervised Change-Detection Methods for Remote-Sensing Images
An unsupervised change detection problem can be viewed as a classification problem with only two classes corresponding to the change and no-change areas, respectively. Thanks to its simplicity, image differencing is a widely used approach to change detection. It is based on the idea of generating a difference image that represents the modulus of the spectral change vector associated with each p...
متن کاملAutomated Change Detection from High-resolution Remote Sensing Images
A fast detection of change in areas of crises or catastrophes is an important condition for planning and coordination of help. This paper describes the results of a cooperative suite of algorithms for automated change detection based on the availability of new satellites with high temporal and/or spatial resolutions. The methods are based on frequency and texture analysis, and segmentation. For...
متن کاملOn Automatic Threshold Selection in Regression Method for Change Detection in Remote Sensing Images
Automatic threshold selection in regression method of change detection in remote sensing images is investigated in this paper. We have reviewed the three well-known automatic threshold selection methods in the image processing field; namely, convex hull, Otsu, and ISODATA. We have then described the adaptive threshold selection concept. We have then shown that from these three methods, only the...
