Objective
2
Few-shot semantic segmentation is one of the fundamental and challenging tasks in the field of computer vision. It aims to use a limited amount of annotated support samples to guide the segmentation of unknown objects in a query image. Compared with traditional semantic segmentation， few-shot semantic segmentation methods effectively alleviate problems， such as the high cost of per-pixel annotation greatly limiting the application of semantic segmentation technology in practical scenarios and the weak generalization ability of this model for novel class targets. The existing few-shot semantic segmentation methods mainly utilize the meta-learning architecture with dual-branch networks， where the support branch consists of the support images and their corresponding per-pixel labeled ground truth masks， and the query branch takes the input of the new image to be segmented， and both branches share the same semantic classes. The valuable information of support images in the support branch is extracted to guide the segmentation of unknown novel classes in query images. However， different instances of the same semantic class may have variations in appearance and scale， and the information extracted solely from the support branch is insufficient to guide the segmentation of unknown novel classes in query images. Although some researchers have attempted to improve the performance of few-shot semantic segmentation through bidirectional guidance， existing bidirectional guidance models overly rely on the pseudo masks predicted by the query branch in the intermediate stage. If the initial predictions of the query branch are poor， it can easily lead to a weak generalization of shared semantics， which is not conducive to improving segmentation performance.
Method
2
A multiscale feature fusion and cross-guidance network for few-shot semantic segmentation is proposed to alleviate these problems， attempting to construct the information interaction between the support branch and the query branch to improve the performance of the few-shot semantic segmentation task. First， a set of pretrained backbone networks with shared weights are used as feature extractors to map features from the support and query branch into the same deep feature space， and then the low-level， intermediate-level， and high-level features output by them are fused at multiple scales to construct a multiscale feature set， which enriches the semantic information of features and enhances the reliability of the feature expression. Second， with the help of the ground-truth mask of the support branch， the fused support features are decomposed into the target-related foreground feature maps and task-irrelevant background feature maps. Then， a feature interaction module is designed on the basis of the cross-attention mechanism， which establishes information interaction between the target-related foreground feature maps of the support branch and the entire query branch feature map， aiming to promote the interactivity between branches while enhancing the expressiveness of task-related features. In addition， a mask average pooling strategy is used on the interactive feature map to generate a target foreground region prototype set， and a background prototype set is generated on the support background feature map. Finally， the cosine similarity measure is used to calculate the similarity values between the support features and the prototype sets and between the query features and the prototype sets； then， the corresponding mask is generated on the basis of the maximum similarity value at each position.

Experimental results on the classic PASCAL-5
i
（pattern analysis， statistical modeling and computational learning） dataset show that when Visual Geometry Group（VGG-16）， residual neural network（ResNet-50）， and ResNet-101 are used as backbone networks， the proposed few-shot semantic segmentation model achieves mean intersection over union （mIoU） scores of 50.2%/53.2%/57.1% and FB-IoU scores of 68.3%/69.4%/72.3% in
the one-way one-shot task and mIoU scores of 52.9%/55.7%/59.7% and FB-IoU scores of 69.7%/72.5%/74.6% in the one-way five-shot task. Results on the more challenging COCO-20i dataset show that the proposed model achieves mIoU scores of 23.9%/35.1%/36.4% and FB-IoU scores of 60.1%/62.4%/64.1% in the one-way one-shot task and mIoU scores of 32.5%/37.3%/38.3% and FB-IoU scores of 64.2%/66.2%/66.7% in the one-way five-shot task when VGG-16， ResNet-50， and ResNet-101 are used as backbone networks. Furthermore， the performance gains of the proposed few-shot semantic segmentation model on the PASCAL-5
i
and COCO-20
i
（common objects in context） datasets are competitive.
Conclusion
2
Compared with current mainstream few-shot semantic segmentation models， our model can achieve higher mIoU and FB-IoU in one-way one-shot and one-way five-shot tasks， with remarkable improvement in overall performance. Further validation shows that feature interaction between the support branch and query branch can effectively improve the model’s ability to locate and segment unknown new classes in query images， and using joint loss between support branch and query branch can promote information flow between dual-branch features， enhance the reliability of prototype expression， and achieve alignment of cross-branch prototype sets.
