hi!

Is there any method to set the Resolution of Mat type image to 300dpi in OpenCV-3.0 before passing it to Tesseract-OCR for further text recognition?

Thanks..

dpi (dots per inch) is a measurement of your pixel's size (used in displaying, or printing). I do not see any use in OCR. If you want to change resolution of your input image of the OCR, you should use resize.
