OmniHandwritingOCR - Single-Line Formulas: leaderboard
A subset of OmniHandwritingOCR (East China Normal University, 2026): 15,096 single-line handwritten mathematical expressions from CROHME, HME100K and MLHME, filtered toward hard samples. Systems transcribe each image to Markdown zero-shot, scored by 1-NED, one minus the normalized edit distance to the ground truth, in percent; higher is better.
Metric: 1-NED (%; one minus the normalized Levenshtein distance between the transcription and the ground truth, averaged over 15,096 single-line handwritten formula images (CROHME, HME100K, MLHME); zero-shot Markdown transcription from one image with one task-neutral instruction for every system; task-specific normalization and tokenization, no semantic correction).
