Information Extraction Method of Alpine Glaciers with Multitemporal and Multiangle Remote Sensing

A glacier extraction method based on multitemporal and multiangle remote sensing images is proposed. Firstly, a "global-local" threshold segmentation method is applied to extract snow ice boundaries with multitemporal remote sensing images. Secondly, the glacier boundaries hidden by mounta...

Firstly, a "global-local" threshold segmentation method is applied to extract snow ice boundaries with multitemporal remote sensing images.
