Are you using c++ Tesseract API ? In mycase i'm using PSM = 11 ,4,5 api->SetPageSegMode(tesseract::PSM_SINGLE_BLOCK); api->SetPageSegMode(tesseract::PSM_SPARSE_TEXT); api->SetPageSegMode(tesseract::PSM_SINGLE_COLUMN);
I think psm =4 have good result words of sentences and psm=11 have good ocr result. Idk hows it's work? but if you have problem with missing words or sentences you must try change the default psm value, Vào 13:33:28 UTC+9 Thứ Tư, ngày 23 tháng 8 năm 2017, Nirajan Pant đã viết: > > I am working on GUI for tesseract OCR 4.0.0 (Nepali Language).
