1. DBNet

Real-time scene text detection with differentiable binarization

• Previous Work
  • Pixel embedding
  • Progressive scale expansion (PSENet)

Idea : Adaptive thresholding

→ 글자영역 경계부분에서만 높은 임계치를 사용

2. MOST

MOST:AMulti-OrientedSceneTextDetectorwithLocalizationRefinement.

• Text Feature Alignment Module (TFAM)
• Position-Aware NMS (PA-NMS)
• Instance-wise IoU loss

3. TextFuseNet

• Semantic Segmentation Branch → Global Level Feature
• Multi-path fusion
