最佳 OCR API — 开源对开发者的局限性

Many developers start with Tesseract, EasyOCR, or PaddleOCR for text extraction due to their free and easy setup. However, their limitations become apparent when dealing with non-standard text. Tesseract is the most widely used OCR tool, supporting over 100 languages, but it struggles with handwriting, rotation, and shadows, requiring manual preprocessing. EasyOCR performs better on scene text than Tesseract but is slower and has large model downloads, relying on PyTorch. PaddleOCR offers the best accuracy among open-source tools but still has some limitations. Developers need to weigh the pros and cons of open-source solutions versus managed APIs when choosing the right tool.
