This is my first encounter with Scribe.js; since I have many book scans I always try OCRing them when I see this. Compared to Tesseract (which is the best I have so far), it gets the words right slightly more, but the paragraph segmentation is many times worse. On a book where every paragraph is indented, it reliably decides two consecutive one-line paragraphs are the same paragraph, which is understandable, but a downgrade from Tesseract which gets the paragraph segmentation as correct as possible (It doesn't handle paragraphs that spanpage-breaks, since I'm feeding it one page at a time)
- Elucalidavah 1y ago> Tesseract (which is the best I have so far) Have you looked at EasyOCR?
- aidenn0 1y agoEasyOCR is significantly worse than Tesseract for clean printed text and , while being orders of magnitude slower; far better than Tesseract for low-quality clean scans and extracting text from pictures (e.g. comics), which Tesseract does not as well.
- zihotki 1y agoScribe is Tesseract. It uses tesseract.js which is a Web Assembly port of Tesseract. So they in theory should be equal. In practice custom settings or older versions could make a difference.
- criddell 1y agoWhat's the motivation for doing this in the browser? It seems like intentionally choosing a more difficult path to create an inferior result. A native MacOS or Windows application could use the OCR facilities of the operating system and, in my experience, both produce results that are far better than Tesseract.
- Zardoz84 1y agoGenerate the OCR on the fly, in the browser, when you do not have the proper OCR info. As someone that works on public web libraries, I see it useful (but wasteful)
- aidenn0 1y agoThis is only true in the "speed" mode; in the "quality" mode it claims better word recognition than Tesseract on clean scans (which matches my tests): https://github.com/scribeocr/scribe.js/blob/master/docs/scribe_vs_tesseract.md#ocr-quality https://github.com/scribeocr/scribe.js/blob/master/docs/scri...
