• Title: FixMatchSeg: Fixing FixMatch for Semi-Supervised Semantic Segmentation
• Authors: Pratima Upretee, Bishesh Khanal
• Abstract summary: Supervised deep learning methods for semantic medical image segmentation are getting increasingly popular in the past few years. In resource constrained settings, getting large number of annotated images is very difficult as it mostly requires experts. In this work, we adapt a state-of-the-art semi-supervised classification method FixMatch to semantic segmentation task, introducing FixMatchSeg.

• Abstract: Supervised deep learning methods for semantic medical image segmentation are getting increasingly popular in the past few years.However, in resource constrained settings, getting large number of annotated images is very difficult as it mostly requires experts, is expensive and time-consuming.Semi-supervised segmentation can be an attractive solution where a very few labeled images are used along with a large number of unlabeled ones. While the gap between supervised and semi-supervised methods have been dramatically reduced for classification problems in the past couple of years, there still remains a larger gap in segmentation methods. In this work, we adapt a state-of-the-art semi-supervised classification method FixMatch to semantic segmentation task, introducing FixMatchSeg. FixMatchSeg is evaluated in four different publicly available datasets of different anatomy and different modality: cardiac ultrasound, chest X-ray, retinal fundus image, and skin images. When there are few labels, we show that FixMatchSeg performs on par with strong supervised baselines.

  Major limitation of deep learning-based segmentation methods is their lack of robustness to variability in the image acquisition protocol. In most cases, the manual segmentation of medical images requires highly skilled raters and is time-consuming. This thesis introduces new mathematical and optimization methods to mitigate those limitations.

• Reference-guided Pseudo-Label Generation for Medical Semantic Segmentation [25.76014072179711]
  We propose a novel approach to generate supervision for semi-supervised semantic segmentation. We use a small number of labeled images as reference material and match pixels in an unlabeled image to the semantics of the best fitting pixel in a reference set. We achieve the same performance as a standard fully supervised model on X-ray anatomy segmentation, albeit 95% fewer labeled images.

  We present a novel semi-supervised 2D medical segmentation solution that applies Contrastive Learning (CL) on image patches, instead of full images. These patches are meaningfully constructed using the semantic information of different classes obtained via pseudo labeling. We also propose a novel consistency regularization scheme, which works in synergy with contrastive learning.

• Exposing Semantic Segmentation Failures via Maximum Discrepancy Competition [102.75463782627791]
  We take steps toward answering the question by exposing failures of existing semantic segmentation methods in the open visual world. Inspired by previous research on model falsification, we start from an arbitrarily large image set, and automatically sample a small image set by MAximizing the Discrepancy (MAD) between two segmentation methods. The selected images have the greatest potential in falsifying either (or both) of the two methods. A segmentation method, whose failures are more difficult to be exposed in the MAD competition, is considered better.

• A Few Guidelines for Incremental Few-Shot Segmentation [57.34237650765928]
  Given a pretrained segmentation model and few images containing novel classes, our goal is to learn to segment novel classes while retaining the ability to segment previously seen ones. We show how the main problems of end-to-end training in this scenario are. i) the drift of the batch-normalization statistics toward novel classes that we can fix with batch renormalization and. ii) the forgetting of old classes, that we can fix with regularization strategies.
