How good is tesseract for OCR nowadays? I tried using it a while back and it was nowhere near as good as the online offerings from AWS, Azure and GCP.

- rereasonable 3y agoLast update was pretty recent, and the git mentions tesseract 5 as a dep. so it's likely moved on a bit from when you last tried it: https://github.com/tesseract-ocr/tesseract/releases https://github.com/tesseract-ocr/tesseract/releases I suppose it depends on your use-case. For personal tasks like this it should be more than sufficient, and won't need user details/cc or whatever to use it.
- Geee 3y agoI tried it quite recently and it failed on a very basic image. I also tried the iOS Vision API, which also failed. My test case was a clear photo of a book page.
- is_true 3y agoIt requires quite a bit of preprocessing. I've only tried GCP's solution which it's better in my experience
- habosa 3y agoI found it to be surprisingly good and I was very impressed with the in-browser performance. It is very very sensitive to resolution though. Once my images got down to a certain size they produced garbage from Tesseract even though they were very human readable.
