Abstract

Underwater optical images are affected by light attenuation, scattering, noise, etc., resulting in low image quality. Therefore, it is extremely significant to improve image quality and optimize network detection performance for underwater target detection. In this work, a YOLOv8-based underwater target detection method via image enhancement is provided, making full utilization of its advantages in large-scale feature learning. To address the issue of insufficient detection accuracy of the YOLOv8 algorithm on the original optical underwater target dataset, we employ an image fusion-based image enhancement method to improve underwater optical image quality. Combining different weights and scales, this method fuses multiple enhanced images to eliminate scattering and color bias, which enhances target features significantly. The results illustrate that the designed YOLOv8-based algorithm via image enhancement improves the precision by 20.5% and exhibits better performance in small, multiple and overlapping targets scenarios, where this algorithm gives a promising way for underwater optics target detection.
