Seg-CFT: Segmentor-guided Counterfactual Fine-Tuning

Outline

This paper explores techniques for training data augmentation, dataset bias removal, and counterfactual image generation for disease modeling. Specifically, we focus on structure-specific interventions (e.g., altering lung area in chest radiographs), highlighting the limitations of existing methods and proposing a novel approach, Seg-CFT. Seg-CFT addresses the complexity of requiring user-provided pixel-level label maps and generates locally consistent and effective counterfactual images while maintaining simple interventions for structure-specific variables. We present promising results for chest radiograph generation and coronary artery disease modeling.
