OCR-D
OCR-D-compliant page segmentation
Hi, I think I have found a bug in `ocrd-segment-extract-lines`: I cannot prove to 100%, but I think I see my environment, that the lines are not extracted (no images...
Version 0.1.20, ocrd/core 2.33.0 I have a PAGE file, which does not have any real content - like this: ``` ``` If I call `ocrd-segment-extract-lines`, I get an expection like...
> If I understand correctly the idea behind these metrics are taken from "rethinking semantic segmentation evaluation" paper, but could you explain to me how could I obtain AP,TPs,FPs,FNs for...
The multi-match overlap algorithm (necessary to calculate over- and undersegmentation) still has a glitch: it will create fake/redundant pairings if either side has a segmentation that already overlaps locally. For...
Even if we lack a free GUI, we should strive to generate [the layouteval schema](http://schema.primaresearch.org/PAGE/eval/layout/2019-07-15) from [PAGE](https://github.com/PRImA-Research-Lab/PAGE-XML/blob/master/layout-evaluation/schema/layouteval.xsd) as evaluation report. Currently, our output looks like this: example report ```JSON {...
ocrd-segment-repair has the optional operations "plausibilize" and "sanitize" – I have no idea what this exactly does :) I would prefer something like this: * shrink-regions-to-hull-of-lines * whatever-plausibilize-does There seems...
I processed the data from the diverse dataset with ~1000 images from the dropbox. The diff will be unreadable and github does not like to show large Notebooks, so I...
(... if line detection took place)
We should have heuristics to check for - polygon containment (overlapping regions, word outside line etc.) - artifacts from annotation like point or line-like regions - lines with (way) too...
