弱监督的语义分割论文汇总
弱监督语义分割导读
一般认为，图像级的标注是弱标注（例如图像分类的类别标注），像素级的标注是强标注（例如分割标注的mask标注），对于普通的分割任务来说：
- 数据是图像，标注是mask，这属于完全监督问题Supervised；
- 如果标注是annotations或者图像级标注，这属于弱监督问题Weakly-supervised；
- 如果标注只有少部分是mask，剩余是annotations或者图像级标注，这属于半监督问题Semi-supervised。
常见的弱标注：bounding box（检测框），scribbles（涂鸦），points（点），image-level labels（图像级别）。利用弱标注可以显著的减少标注时间，如果可以利用弱标签就可以获得与mask标签不相上下的精度和准确率，那我们利用弱标签和弱监督将会促进产品和数据的迭代。我们按照不同的弱标签–>语义分割的标签mask做一下整理 ⬇️。
ps：我们聚焦于语义分割，实例分割和全景分割也有很多成果，并未在本篇博客中列出。
弱监督语义分割论文整理
基于Bounding box的弱监督语义分割
利用深度学习方法和bounding box作为弱标签的语义分割研究，之前，基于Bounding box的分割以Grabcut这类算法一枝独秀，但是效果虽然有突破但不甚理想，所以2016年的Deepcut对于Grabcut做了进一步的优化得到了较好的效果。2015年ICCV中的BoxSup算作是开山之作（He,K为二作的又一次大佬的实力展现），但其中需要以无监督获取到的Candidate mask来迭代更新标签。在这一想法上，发表于2020年CVPR的Self-correcting Networks可以说是将这一想法又往前推进了一步（其实这个工作2018年就已经初见雏形，但2020年才正式发表），将金字塔模型、辅助分割模型和自矫正模块结合在一起，不过这个网络里面有少部分的全监督数据。

基于Image-level labels的弱监督语义分割
基于Image-level labels的弱标签主要是图像分类标签（同理可以扩展到视频分类中），目前，大多数的基于图像分类标签来进行的弱监督语义分割研究的思路：将对图像分类标签响应最强烈的区域作为最初始的种子，通过不同的扩张手段得到更多的区域，从而得到分割的mask。在此过程中，和传统的机器学习算法结合比较多，因为需要得到底层特征的相关性。
