Best OCR by Text Extraction Accuracy in 2021

Optical Character Recognition (OCR) is a field of machine learning that is specialized in distinguishing characters within images like scanned documents, printed books, or photos. Although it is a mature technology, there are still no OCR products that can recognize all kinds of text 100% accurately. Among the products that we benchmarked, only a few products could output successful results from our test set. OCR tools are used by companies to identify texts and their positions in images, classify business documents according to subjects, or conduct key-value pairing within documents. Based on OCR results, other technology companies build applications like document automation. For all these business cases, accurate text recognition is critical for an OCR product.
