tesseract OCR have a command line interface, which allow us to recognize text from images with some parameters.
Input argumetns are imagename (path to image) outputbase (name of recognized text) and -psm pagesegmode parameters.
pagesegmode values are:
0 = Orientation and script detection (OSD) only.
1 = Automatic page segmentation with OSD.
2 = Automatic page segmentation, but no OSD, or OCR
3 = Fully automatic page segmentation, but no OSD. (Default)
4 = Assume a single column of text of variable sizes.
5 = Assume a single uniform block of vertically aligned text.
6 = Assume a single uniform block of text.
7 = Treat the image as a single text line.
8 = Treat the image as a single word.
9 = Treat the image as a single word in a circle.
10 = Treat the image as a single character.
-l lang and/or -psm pagesegmode must occur before anyconfigfile.
But can it library write positions and sizes of recognized text blocks to the specific file or it is an internal information?
