Abstract
The linear unmixing technique is investigated for change detection in multitemporal airborne hyperspectral imagery. Several practical implementation issues are discussed. The preliminary study using the CASI data shows its feasibility when the noise level is moderate and some prior information about endmembers is known. Keywords— linear mixture model; unsupervised linear unmixing; change detection; multitemporal airborne hyperspectral imagery.
