The tool dinglehopper-extract extracts the text of the given input file on stdout, for example: dinglehopper-extract -textequiv-level line OCR-D-GT-PAGE/Īs a OCR-D processor: ocrd-dinglehopper -I OCR-D-GT-PAGE,OCR-D-OCR-TESS -O OCR-D-OCR-TESS-EVAL This generates report.html and report.json. textequiv-level LEVEL PAGE TextEquiv level to extract text fromįor example: dinglehopper some-document.gt.page.xml metrics / -no-metrics Enable/disable metrics and green/red Use '-textequiv-level line' to extract from the level of TextLine tags. The reports include the characterĮrror rate (CER) and the word error rate (WER).īy default, the text of PAGE files is extracted on 'region' level. The comparison report will be written to $REPORT_PREFIX., where In that case, use -no-metrics to disable the then meaningless metrics andĪlso change the color scheme from green/red to blue. The files GT and OCR are usually a ground truth document and the result ofĪn OCR software, but you may use dinglehopper to compare two OCR results. Their text and falls back to plain text if no ALTO or PAGE is detected. Usage Usage: dinglehopper GT OCR Ĭompare the PAGE/ALTO/text document GT against the document OCR.ĭinglehopper detects if GT/OCR are ALTO or PAGE XML documents to extract It's best to use pip, e.g.: sudo pip install. It compares a ground truth (GT) document page with a OCR result page to compute metrics and a word/character differences report. Dinglehopper is an OCR evaluation tool and reads ALTO, PAGE and text files.
