Outline Generation Transformer for Bilingual Scene Text Recognition
Bibliographic record
Abstract
We propose the Outline Generation Transformer (OGT) for bilingual Scene Text Recognition (STR). As most STR approaches focus on English, we consider both English and Chinese as Chinese is also a major language, and it is a common scene in many areas/countries where both languages can be seen. The OGT consists of an Outline Generator (OG) and a transformer with a language model embedded. The OG detects the character outline of the text and embeds the outline features into a transformer with the outline-query cross-attention layer to better locate each character and enhance the text recognition performance. The training of OGT has two phases, one is training on synthetic data where the text outline masks are made available, followed by the other training on real data where the text outline masks can only be estimated. The proposed OGT is evaluated on several benchmark datasets and compared with state-of-the-art methods.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
