Weakly supervised video anomaly detection is of great importance to security surveillance. The task detects anomaly with solely video-level labels. Despite significant progress made by existing methods, they have the following limitations: On one hand, they pay little attention to the specific spatial regions where ano...

Multibeam sonar is an important sensing modality for submerged reef detection, with potential applications in ROV operations, navigation safety, and offshore engineering. However, dedicated public acoustic datasets with object-level annotations for submerged reef or reef-like target detection remain limited, restrict...

Accurate near-field underwater visual perception plays a crucial role in marine ecological monitoring and benthic resource exploration. However, the superimposition of the biomimetic characteristics of benthic organisms and the optical degradation caused by the water medium frequently induces significant underwater v...
