Researchers have developed a new metric called Consensus Entropy (CE) to assess the reliability of Optical Character Recognition (OCR) outputs from Vision-Language Models (VLMs). CE measures the agreement between multiple VLMs, hypothesizing that correct predictions will have consistent outputs while errors will diverge. This metric is training-free and can be integrated into a framework called CE-OCR, which uses ensemble agreement to verify and select high-quality OCR results, reportedly improving F1 scores by over 42% compared to using a VLM as a judge.
