for text detection we used EAST (An efficient and accurate scene text detector)

we simply merge the bounding boxes into a larger one most probably it will be the title

we apply only the title image to EAST

we use tesseract for text recognition for thr image

The output text:
(THIRD EDITION Textbook of Geotechnical Enoineering)

we applied some simple text processing methods:
-removing punctuation.
-removing single characters from the list of results.
-removing duplication.
