iQIYI AI Bullet‑Screen Masking: Semantic Segmentation System and Engineering Insights

iQIYI’s bullet‑screen masking employs a DeepLabv3+‑based two‑class semantic segmentation pipeline, preceded by a close‑up detector and followed by morphological refinement, trained on a custom annotated dataset that raises IoU to 93.6 %, processes hour‑long videos in under an hour, and is slated for future upgrades to instance and panoptic segmentation for finer‑grained masking.
