Range estimation of low-frequency underwater acoustic target based on deep learning architecture with data augmentation
Accurate underwater acoustic ranging is critical for numerous applications, yet traditional methods often struggle with precision and adaptability. This study introduces a novel approach utilizing a ResNet-UNet architecture enhanced by data augmentation to estimate the range of low-frequency underwater targets. Leveraging covariance matrix data, the method significantly improves accuracy, notably outperforming matched field processing and conventional neural networks, even under challenging signal conditions. Experimental validation using SWellEX-96 data demonstrates the efficacy of this integrated data ecosystem.
Improving cross-flight plastic litter segmentation with ConvNeXt V2 U-Net for UAV SWIR hyperspectral imagery
Accurate spatial monitoring of plastic litter is crucial for effective ecosystem management, and UAV short-wave infrared (SWIR) hyperspectral imagery offers high-resolution detection capabilities. However, cross-flight variability often limits operational utility. This study addresses this challenge by presenting a novel framework utilizing a compact ConvNeXt V2-based U-Net, achieving significant improvements in plastic litter segmentation across diverse acquisition conditions. Results demonstrate a substantial increase in Dice score (78.2%) and IoU (64.
