CHANGE DETECTION IN LAND USE AND LAND COVER OF DISTRICT CHARSADDA PAKISTAN ALONG RIVER KABUL (2010 FLOOD): TAKING ADVANTAGE OF GEOGRAPHIC INFORMATION SYSTEM AND REMOTE SENSING [PDF]

open access: yesGeological Behavior, 2021
This study aims to quantify land use and land cover changes before and after the 2010 flood in district Charsadda, Pakistan. Advanced geographic information systems (GIS) and remote sensing techniques (RST) evaluate land use and land cover changes.

Spaceborne SAR Time-Series Images Change Detection Based on SAR-SIFT-Logarithm Background Subtraction

open access: yesRemote Sensing, 2023
Synthetic Aperture Radar (SAR) image change detection aims to detect changes with images of the same area acquired at different times. It has wide applications in environmental monitoring, urban planning and resource management.

Data-Efficient Minimax Quickest Change Detection with Composite Post-Change Distribution [PDF]

open access: yes, 2014
The problem of quickest change detection is studied, where there is an additional constraint on the cost of observations used before the change point and where the post-change distribution is composite. Minimax formulations are proposed for this problem.

Hierarchical Change-Detection Tests [PDF]

open access: yesIEEE Transactions on Neural Networks and Learning Systems, 2017
We present hierarchical change-detection tests (HCDTs), as effective online algorithms for detecting changes in datastreams. HCDTs are characterized by a hierarchical architecture composed of a detection layer and a validation layer. The detection layer steadily analyzes the input datastream by means of an online, sequential CDT, which operates as a ...

Effects of search intent on eye-movement patterns in a change detection task

open access: yesJournal of Eye Movement Research, 2015
The goal of the present study was to examine whether intention type affects eye movement patterns in a change detection task In addition, we assessed whether the eye movement index could be used to identify human implicit intent. We attempted to generate

Binary Change Guided Hyperspectral Multiclass Change Detection

open access: yesIEEE Transactions on Image Processing, 2023
Characterized by tremendous spectral information, hyperspectral image is able to detect subtle changes and discriminate various change classes for change detection. The recent research works dominated by hyperspectral binary change detection, however, cannot provide fine change classes information.

Change probability-aware graph for multimodal change detection

open access: yesGeo-spatial Information Science
Multimodal change detection (MCD) has emerged as a pivotal technology for monitoring surface changes based on remote sensing images. Recently, many graph structure-based methods have been proposed, leveraging the construction and comparison of consistent

Fade-in and fade-out detection in video sequences using histograms [PDF]

open access: yes, 2000
There is an increased need to extract key information automatically from video for the purposes of indexing, fast retrieval, and scene analysis. To support this vision, reliable scene change detection algorithms must be developed. Several algorithms have
