You Actually Look Twice At it (YALTAi): using an object detection approach instead of region segmentation within the Kraken engine [article]

Thibault Clérice
2022 arXiv   pre-print
The ability of identifying main body of text from marginal text or running titles makes the difference between extracting the work full text of a digitized book and noisy outputs.  ...  We propose to shift, for efficiency, the task from a pixel classification-based polygonization to an object detection using isothetic rectangles.  ...  I INTRODUCTION In recent years, automatic text extraction has become an important activity in digital philology and, in general, in corpus creation for historical documents.  ...
