摘要

摘要: 针对轻量化目标模型SSD-MV2对水下光学图像感兴趣目标检测精度低的问题，该文提出一种通道可选择的轻量化特征提取模块(SEB)和一种卷积核可变形、通道可选择的特征提取模块(SDB)。与此同时，利用SEB模块和SDB模块分别重新设计了SSD-MV2的基础网络和附加特征提取网络，记作SSD-MV2SDB，并为其选择了合理的基础网络扩张系数和附加特征提取网络SDB模块数量。在水下图像感兴趣目标检测数据集UOI-DET上，SSD-MV2SDB比SSD-MV2检测精度提高3.04%。实验结果表明，SSD-MV2SDB适用于水下图像感兴趣目标检测任务。

Abstract: In order to solve the problem of low detection accuracy of SSD-MV2, a Selective and Efficient Block (SEB) and a Selective and Deformable Block (SDB) are proposed. At the same time, the basic network and additional feature extraction network of SSD-MV2 are redesigned by using SEB and SDB, which is named SSD-MV2SDB, and a set of reasonable expansion coefficient of basic network and number of SDB in additional feature extraction network are selected for SSD-MV2SDB. On UOI-DET, mAP of SSD-MV2SDB is 3.04% higher than that of SSD-MV2. The experimental results show that SSD-MV2SDB is suitable for underwater optical image interested object detection task.
