A novel fire index-based burned area change detection approach using Landsat-8 OLI data

European Journal of Remote Sensing, 2020
Change detection from multi-temporal remote sensing images is an effective way to identify the burned areas after forest fires. However, the complex image scenario and the similar spectral signatures in multispectral bands may lead to many false positive

A detection theory account of change detection

Journal of Vision, 2004
Previous studies have suggested that visual short-term memory (VSTM) has a storage limit of approximately four items. However, the type of high-threshold (HT) model used to derive this estimate is based on a number of assumptions that have been criticized in other experimental paradigms (e.g., visual search).
