You don't say what resolution or format images, what language(s), what version of Tesseract -- all of which are pretty critical when discussing performance. Having said that, I just ran a 110 page document in 272 seconds on a recent MacBook Pro. There were ~100 pages of mixed density text totalling 160k characters in CCITT G4 fax bitonal images of 2550x3300 pixels. That's four times the speed you quote, so I suspect you're reinitializing Tesseract for every page or taking a big hit on image processing or something else unrelated to the core OCR engine. > > *Training* > I am trying to learn about training Tesseract for improved accuracy. > Given that the fonts / box files used to generate eng.traindata are not > available can one specify the fonts used for english? > The font list is included in the eng.inttemp file that you extracted. Given that it's something like 350 fonts, you'd have to be looking at a pretty exotic font to need to retrain for that reason. > Also, is there a description of the various training artifacts ?
