Show HN: Screenshot Hero - iPhone app to make all photos text searchable
Based on the video it works amazingly well. I’ve tried finding a usable way for open source text recognition on desktop, and haven’t found anything even close to this.<p>Like, I've got scans of letters, machine-written, 300dpi, perfect black/white 1-bit depth, no marks or scratches, perfect quality — and OCRmyPDF (using tesseract) absolutely fails at this task, returning only bullshit. Even if I set the language correctly, or even set the wordlist to a manual transcription of the PDF.<p>I also tried using OCR on screenshots, with the same miserable result.<p>How does Apple’s Vision API do so much better at this kind of task? Is there some trick I'm missing?<p>Like, the images I supply are of such high quality that you can literally just split into characters and search for the nearest match in a database of latin characters, and even that would return better results than tesseract.
