Tesseract doesn't care about whether things are metal or plastic or cotton, it tries to turn whatever image it is given into text via a pipeline of rules and shape classifiers for text. It succeeds when the text is distinct enough from the background so that it can do that job, and I suspect you will struggle a lot with this image unless you do some preprocessing.
I worked on a project using Tesseract for scanning airplane decals and we had a preprocessing pipeline consisting of gaussian blurring, adaptive thresholding and more. You might look into background removal as a preprocessing stage for this kind of image to give Tesseract a better chance of seeing just the text: http://docs.opencv.org/3.1.0/db/d5c/tutorial_py_bg_subtraction.html#gsc.tab=0 Cheers On 21 July 2016 at 12:24, Mark Greally <[email protected]> wrote: > Hi. > > I have just started using tesseract and have successfully read printed > text on paper.
