Tesseract + gscan2pdf : l’ocr 5 étoiles.

Je me suis basé sur un article publié par « Linux on the root« , en l’adaptant pour mon archlinux.

L’installation des logiciels est assez simple :

yaourt -S tesseract gscan2pdf

Ensuite, en lançant gscan2pdf, on peut numériser – 300 dpi étant pratique pour avoir une bonne reconnaissance – ou récupérer une image numérisée.

Et j’avoue que le résultat est franchement… étonnant. Bref, mon précédent billet semble être un peu trop « éjaculation précoce » 😉

Mais que va-t-il rester aux logiciels propriétaires, mis à part les bonnes grosses daubes ludiques ? 😉

un preparation for Hate Week. The Hat was seven flights
up, mul Winston, who was thirty-nine and had a varicose
ulcer nhovc his right ankle, went slowly, resting several
Ilmes on thc way. On each landing, opposite the lift shaft,
the poster with the enormous face gazed from the wall. It
