AI Technical Summary

Technical Problem

Existing technologies have low detection accuracy in detecting small targets at sea due to interference from complex sea conditions, and their robustness is poor, especially in environments with waves, changes in lighting, and sea fog.

Method used

By dynamically adjusting the threshold parameters and kernel size of the image detection kernel, combined with multi-channel stitching and multi-level cross-channel attention extraction, a trained small target detection model is used to detect small targets at sea, adaptively suppressing noise and extracting edge features.

Benefits of technology

It improves the robustness and accuracy of small target detection at sea, enabling accurate identification of small targets under complex sea conditions.
