Small object detection in side-scan sonar images based on SOCA-YOLO and image restoration

Frontiers in Marine Science
Although side-scan sonar can provide wide and high-resolution views of submarine terrain and objects, it suffers from severe interference due to complex environmental noise, variations in sonar configuration (such as frequency, beam pattern, etc.), and ...
