One thing that improves Tesseract's performance dramatically is giving it grayscale tif images. Do
mogrify -type Grayscale *.tif
and run them through tesseract to see the difference. No idea why no one mentions this in the documentation.
- mgedmin 16y agoI've found that Tesseract's accuracy was much improved when I converted my grayscale images to bitmaps with GIMP's Threshold tool. (Those pictures were not-very-hight quality snaps of a few pages of a book taken with a 3.2 Mpix digital camera.)
- hijimayor 16y agoTesseract really wasn't made for camera pics, but it could use some help with the thresholding :)
