OCR comparison: Tesseract versus EasyOCR vs PaddleOCR vs MMOCR

A comparative analysis of four popular open-source OCR engines: Tesseract, EasyOCR, PaddleOCR, and MMOCR. The comparison evaluates text detection and recognition capabilities using a test document from the FUNSD dataset. PaddleOCR shows superior performance in text detection with slanted bounding boxes and better recognition accuracy, while Tesseract struggles with text detection and word segmentation. The analysis highlights that OCR performance varies significantly depending on the specific use case and document type.
