Few-shot Metro Track-wheel Image Segmentation Algorithm Based on Cross-attention Network by CAO Jianxin, ZHANG Yueying, JIANG Weihao, GAO Yunhao

“…A cross-attention network is used to mine the relational semantics between these fused features, enabling the capture of shared semantic information in the deep space across different metro track-wheel images belonging to the same class. Finally, an average pooling is applied to convert the common features of both branches into class-specific prototypes, and the prototypes are leveraged to guide the segmentation of unannotated track-wheel images in the query images. …”
