Groundtruth for Text Binarization Models

To prepare the images for SAM-fine-tune, I ran this command on all of the images:

for img in *; do name="${img%.*}" convert "$img" -alpha off -type TrueColor png24:"$name".png; done

To convert them all to RGB PNG files with no transparency.

Bleed-Through Database

• Did not use UCD.MSA29.12v as it was too messy and cleaned up NLI.MSG18.147 manually.

Palm Leaf Manuscript Dataset

• The lines are accurate in path but not thickness.

DIVA-HisDB

• Too innacurate for use here.
