The system pairs a Hybrid Attention Transformer super-resolution (HAT) front-end with an ensemble of two scene-text recognisers (PARSeq-S and CLIP4STR-B) and a confidence-weighted character-voting scheme that abstains on uncertain positions. We treat XLPSR as a recognition task gated by image legibility: the SR step exists to lift characters out of sub-pixel territory, and the asymmetric scoring rule (+2 / -1 / 0) is exploited explicitly through abstention. Our pipeline runs in 1.7 s per sequence on RTX 3090 (max 2.7 s, p99 2.4 s), well under the 60 s/sequence Docker budget.", "url": "https://wpnews.pro/news/hat-super-resolution-and-a-parseq-clip4str-voting-ensemble-for-extreme-in-the", "canonical_source": "https://arxiv.org/abs/2607.08896", "published_at": "2026-07-13 04:00:00+00:00", "updated_at": "2026-07-13 04:24:48.601404+00:00", "lang": "en", "topics": ["computer-vision", "machine-learning", "artificial-intelligence"], "entities": ["HAT", "PARSeq", "CLIP4STR", "ICIP", "RTX 3090"], "alternates": {"html": "https://wpnews.pro/news/hat-super-resolution-and-a-parseq-clip4str-voting-ensemble-for-extreme-in-the", "markdown": "https://wpnews.pro/news/hat-super-resolution-and-a-parseq-clip4str-voting-ensemble-for-extreme-in-the.md", "text": "https://wpnews.pro/news/hat-super-resolution-and-a-parseq-clip4str-voting-ensemble-for-extreme-in-the.txt", "jsonld": "https://wpnews.pro/news/hat-super-resolution-and-a-parseq-clip4str-voting-ensemble-for-extreme-in-the.jsonld"}}
