1 | initial version |
opencv does not deal at all with dpi, which is irrelevant in computer-vision and only needed for printing out things.
imread()
will discard all meta information, and imwrite()
won't write any dpi values.
the value of 90 you see (where ?) in your imageviewer is plain bogus / default (because there never was anything)

and again, neither ocr nor cnns care about dpi, only about pixels and image size.
