Weakly-Supervised Semantic Segmentation

146 papers with code • 9 benchmarks • 8 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.

Weakly Supervised Semantic Segmentation for Large-Scale Point Cloud

dmcv-ecnu/MindSpore_ModelZoo AAAI 2021

Firstly, we construct a pretext task, \textit{i. e.,} point cloud colorization, with a self-supervised learning to transfer the learned prior knowledge from a large amount of unlabeled point cloud to a weakly supervised network.

Constrained-CNN losses for weakly supervised segmentation

LIVIAETS/SizeLoss_WSS 12 May 2018

To the best of our knowledge, the method of [Pathak et al., 2015] is the only prior work that addresses deep CNNs with linear constraints in weakly supervised segmentation.

Weakly Supervised Learning of Instance Segmentation with Inter-pixel Relations

jiwoon-ahn/irn CVPR 2019

For generating the pseudo labels, we first identify confident seed areas of object classes from attention maps of an image classification model, and propagate them to discover the entire instance areas with accurate boundaries.

Puzzle-CAM: Improved localization via matching partial and full features

OFRIN/PuzzleCAM 27 Jan 2021

Weakly-supervised semantic segmentation (WSSS) is introduced to narrow the gap for semantic segmentation performance from pixel-level supervision to image-level supervision.

Weakly- and Semi-Supervised Learning of a DCNN for Semantic Image Segmentation

deeplab/deeplab-public 9 Feb 2015

Deep convolutional neural networks (DCNNs) trained on a large number of images with strong pixel-level annotations have recently significantly pushed the state-of-art in semantic image segmentation.

Learning without Exact Guidance: Updating Large-scale High-resolution Land Cover Maps from Low-resolution Historical Labels

lizhuohong/paraformer 5 Mar 2024

However, it is still a non-trivial task hindered by complex ground details, various landforms, and the scarcity of accurate training labels over a wide-span geographic area.

Learning Pixel-level Semantic Affinity with Image-level Supervision for Weakly Supervised Semantic Segmentation

jiwoon-ahn/psa CVPR 2018

To alleviate this issue, we present a novel framework that generates segmentation labels of images given their image-level class labels.

Integral Object Mining via Online Attention Accumulation

PengtaoJiang/OAA-PyTorch ICCV 2019

In order to accumulate the discovered different object parts, we propose an online attention accumulation (OAA) strategy which maintains a cumulative attention map for each target category in each training image so that the integral object regions can be gradually promoted as the training goes.

Self-supervised Equivariant Attention Mechanism for Weakly Supervised Semantic Segmentation

YudeWang/SEAM CVPR 2020

Our method is based on the observation that equivariance is an implicit constraint in fully supervised semantic segmentation, whose pixel-level labels take the same spatial transformation as the input images during data augmentation.

Mining Cross-Image Semantics for Weakly Supervised Semantic Segmentation

GuoleiSun/MCIS_wsss ECCV 2020

Moreover, our approach ranked 1st place in the Weakly-Supervised Semantic Segmentation Track of CVPR2020 Learning from Imperfect Data Challenge.
