UnverifiedModern OCR systems such as Tesseract, Google Document AI, and AWS Textract provide spatial coordinates and confidence scores at the granularity of lines, words, and even characters.74% similarUnverifiedTraditional OCR systems typically rely on convolutional neural networks (CNNs) at the underlying level for character segmentation and recognition, with the pipeline being a hardcoded unidirectional flow: image preprocessing → layout analysis → character recognition → post-processing.73% similarUnverifiedThe OCR route commonly uses tools such as Tesseract and PaddleOCR to first obtain plain text and then hand it to a language model to determine the fields; end-to-end vision models (such as Donut and Qwen-VL) skip explicit OCR and predict structured output directly from the image.73% similarUnverifiedPaddleOCR is an OCR tool library open-sourced by Baidu's PaddlePaddle team, supporting text detection and recognition in multiple languages including Chinese and English, with specialized optimization for scenarios such as scanned documents, tilted photos, and low-resolution receipts.72% similar
