CEFS DF-Motion Dataset
This dataset accompanies the CEFS repository for the TPAMI paper "Coded Event Focal Stack for Continuous Refocusing in Dynamic Scene".
Repository: https://github.com/moon-boat/CEFS
Files
test/cefs_df_motion_test.tar.gz: DF-Motion test data archive,1,348,641,112bytes.train/scene_001_events.tar.gz: partial training event data for scene 1,277,472,285bytes.train/scene_001_aif.tar.gz: partial all-in-focus training data for scene 1,91,083,558bytes.
The remaining 30-scene training data is not fully uploaded yet. scene_1/gt alone exceeded 900 MB during compression and did not complete reliably over the current NAS mount, so the full training split should be packaged with a more stable storage path or uploaded in smaller verified parts.
Test Archive Layout
After extracting test/cefs_df_motion_test.tar.gz, the archive contains:
DF-motion/
└── scene_*/
└── 0..15/
├── 0.jpg
├── 1.jpg
└── event.txt
Notes
The CEFS code repository does not bundle dataset files. Current CEFS training loaders expect a normalized JPG / DF-Motion-style layout with scene_*, event_v2e/, gt/, and optional aif/ folders. If this dataset is published in a raw author-archive layout, normalize it to the loader layout documented in docs/data_format.md before running training scripts.
Generated event-stack caches such as event_v2e_stacks/ are intentionally not required; CEFS loaders can regenerate them from event text files.
