New self-supervised sonar imaging technique suppresses noise and blur

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel self-supervised framework for enhancing multibeam imaging sonar data. This method jointly addresses speckle noise and system-induced blur without requiring clean ground truth images. By employing a physics-consistent image-formation model and utilizing registered multi-frame sonar sequences, the framework achieves improved image quality, demonstrating a favorable balance between speckle suppression and the preservation of structural details compared to existing methods. AI

IMPACT This research introduces a novel self-supervised learning approach for image processing, potentially applicable to various sensor data enhancement tasks.

    Self-Supervised Multibeam Sonar Restoration via Coherent Forward Modeling

    arXiv:2610.31490v1 Announce Type: cross Abstract: Multibeam imaging sonar produces intensity images degraded by coherent speckle and system-induced blur, while clean reflectivity targets are rarely available. Existing despeckling methods often rely on simplified intensity-domain …
