The title is a bit misleading (and doesn't match the linked article). This isn't about building an OCR engine, it's about using an existing one.
Yes. We've changed the title to that of the article. From the site guidelines: "Please use the original title, unless it is misleading or linkbait; don't editorialize."
Submitted title was "Building an OCR Engine with Python and Tesseract", which broke that guideline, assuming the page title didn't change.
