Abstract: Deep learning algorithms have been widely applied in the field of image classification. However, the limited availability of side-scan sonar images containing target objects poses a significant challenge in meeting the training demands of these algorithms, often leading to issues like overfitting. Style transfer has emerged as an effective method for augmenting training samples. This paper investigates and reconstructs the iterative processes of the WCT and PhotoWCT style transfer algorithms. Based on the characteristics of Unpooling and Upsampling, we propose modifications to the WCT algorithm across different feature layers of the decoder, resulting in the development of the WCST style transfer algorithm, which is more suited for side-scan sonar imagery.Using the WCST algorithm, realistic pseudo side-scan sonar images containing target objects were generated to meet the training requirements of image classification networks. In subsequent image classification experiments, datasets generated by WCST and PhotoWCT were used to train ResNet50. The results demonstrated that WCST outperformed the other methods in all accuracy metrics, highlighting its effectiveness in augmenting high-quality training sets for side-scan sonar image classification.
