what's the best image input type for tesseract?

I'm using tesseract on a project and want to know the best image input type for tesseract to give the best output. Is Binary&TIFF the best input or there's something else?


  • I had excellent results using TIFF in the past for a similar task. At the time I did some pre-processing using OpenCV and exported the result to a TIFF file that later was sent to tesseract. It was pretty good.
