PPNet(Part-aware Prototype Network for Few-shot Semantic Segmentation)[1] decompose the holistic class representation into a set of part-aware prototypes, and leverage unlabeled data to better modeling of intra-class variations. Besides, graph neural network model is used to generate and enhance the proposed part-aware prototypes. There are some details of reading and implementing it.

PANet(PANet: Few-Shot Image Semantic Segmentation with Prototype Alignment)[1] learns class-specific prototype representations for images and matches each pixel to the learned prototypes. There are some details of reading and implementing it.

CANet(CANet: Class-Agnostic Segmentation Networks with Iterative Refinement and Attentive Few-Shot Learning)[1] consists of a two-branch dense comparison module which performs multi-level feature comparison, and an iterative optimization module which iteratively refines the predicted results. There are some details of reading and implementing it.

SG-One(SG-One: Similarity Guidance Network for One-Shot Semantic Segmentation)[1] adopt a masked average pooling strategy for producing the guidance features, then leverage the cosine similarity to build the relationship. There are some details of reading and implementing it.

co-FCN(Conditional Networks for Few-Shot Semantic Segmentation)[1] handle sparse pixel-wise annotations to achieve nearly the same accuracy. There are some details of reading and implementing it.

OSLSM(One-Shot Learning for Semantic Segmentation)[1] firstly proposed two-branch approach to one-shot semantic segmentation. Conditioning branch trains a network to get parameter $\theta$, and Segmentaion branch outputs the final mask based on parameter $\theta$. There are some details of reading and implementing it.

Mask R-CNN[1] is a framework for object instance segmentation, which adds a branch for predicting an object mask in parallel with the existing branch for bounding box recognition of Faster R-CNN. There are some details of reading and implementing it.
