![]() Good luck, and please let us know what you come up with. If these are the only scenarios, white-on-black is always solid background, and black-on-color is always seven-segment-display, then you're done. ![]() If not, I suspect you could look at image color histograms to at least figure out whether your text is white-on-black or black-on-color. Both of these fonts have a similar clean and modern look, and they’ll work well for any design that. There are a few different fonts that are similar to the San Francisco font, but the two that are most similar are Helvetica Neue and Arial. If you have metadata telling you what sort of display you're dealing with, great. If you’re wondering what font is similar to the San Francisco font on Canva, we’ve got you covered. The hard part then becomes knowing which preprocessing task to do. An easy first pass might be to do a small-radius gaussian blur, threshold at a pretty low value (you're trying to keep only black, so 15% seems right), and then invert the image. Using some image manipulation tool (I happen to like imagemagick), you need to make the images more to tesseract's satisfaction. ![]() It is not very smart about how to do this. If you give it something that isn't that, it will do its best to convert it to that format. Tesseract would really prefer its images to all be white-on-black text in bitmap format. This seems like an image preprocessing task.
