Weakly-Supervised Semantic Segmentation
142 papers with code • 6 benchmarks • 7 datasets
The semantic segmentation task is to assign a label from a label set to each pixel in an image. In the case of fully supervised setting, the dataset consists of images and their corresponding pixel-level class-specific annotations (expensive pixel-level annotations). However, in the weakly-supervised setting, the dataset consists of images and corresponding annotations that are relatively easy to obtain, such as tags/labels of objects present in the image.

Question-Answer Cross Language Image Matching for Weakly Supervised Semantic Segmentation
Class Activation Map (CAM) has emerged as a popular tool for weakly supervised semantic segmentation (WSSS), allowing the localization of object regions in an image using only image-level labels.

In this paper, we propose a novel class activation scheme that is able to uniformly highlight the whole object region.
PointCT: Point Central Transformer Network for Weakly-supervised Point Cloud Semantic Segmentation
Although point cloud segmentation has a principal role in 3D understanding, annotating fully large-scale scenes for this task can be costly and time-consuming.

Building upon this, we introduce a complementary self-enhancement method that constrains the semantic consistency between these confident regions and an augmented image with the same class labels.
Foundation Model Assisted Weakly Supervised Semantic Segmentation
This work aims to leverage pre-trained foundation models, such as contrastive language-image pre-training (CLIP) and segment anything model (SAM), to address weakly supervised semantic segmentation (WSSS) using image-level labels.
Weakly Supervised Semantic Segmentation by Knowledge Graph Inference
