Estimating River Discharge from Remotely Sensed River Widths in Arid Regions of the Northern Slope of Kunlun Mountain Open
Arid-region water resource management is hindered by severely inadequate river discharge monitoring, with effective observations of hydrological processes particularly lacking in narrow river channels. To overcome this bottleneck, this stu…

CAFR-Net: A transformer-contrastive framework for robust spinal MRI segmentation via global-local synergy Open
Automated spinal structure segmentation in sagittal MRI remains a non-trivial task due to high inter-patient variability and ambiguous anatomical boundaries. We propose CAFR-Net, a Transformer-contrastive hybrid framework that jointly mode…

Accurate Wide Angle SAR Imaging Based on LS-CS-Residual Open
Wide angle synthetic aperture radar (WASAR) receives data from a large angle, which causes the problem of aspect dependent scattering. L 1 regularization is a common compressed sensing (CS) model. The L 1 regularization based WASAR imaging…
