针对水下目标检测任务中图像模糊,背景复杂以及目标小而导致误检和漏检问题,提出一种改进YOLOv3-SPP的水下目标检测算法.利用UWGAN网络对水下原始图像进行恢复,采用Mixup方法增强数据,减少错误标签记忆;以YOLOv3-SPP网络结构为基础,增加网络预测尺度,提高小目标检测性能;引入CIoU边框回归损失,提高定位精度;利用K-Means++...
To solve the problem of faulty and omitted detection that results from blurred images, complex backgrounds and small targets in underwater target detection tasks, an improved YOLOv3-SPP underwater target detection algorithm is proposed. Firstly, the original underwater image is recovered by U...
