Asynchronous Acoustic–Image Classification for Unattended Ground Sensors with Domain Adaptation and Bidirectional Prototype Distillation

Acoustic and image sensors in unattended ground sensor systems often operate at different sampling rates and use different trigger mechanisms and fields of view, so their observations are asynchronous and lack instance-level correspondence. In addition, web images used to supplement scarce field annotations exhibit a s...
