Ocr tool meaning pdf#
If the PDF does not contain a text layer, we must process it differently than if it did.Īfter choosing the right pipeline the image comes to the pre-processing step. For example, PDF documents may or may not contain a text layer. For OCR software to work accurately, it must be able to identify different types of documents and run the correct predefined pipeline based on that. The main challenge of text recognition is that each document template has its own set of entities, values, and location of entities in the document. Checking the document type & Image pre-processing The functioning of the traditional optical character recognition system consists of three stages: image pre-processing, character recognition, post-processing. Optical Mark Recognition (OMR) is used to identify the information that people mark on surveys, tests, etc.Optical Word Recognition (OWR) scans typewritten text word by word.Intelligent Character Recognition (ICR) is a more advanced form of OCR based on updating algorithms to gather more data about variations in hand-printed characters.Intelligent Word Recognition (IWR) is used for the recognition of unconstrained handwritten words instead of recognition of individual characters.There are different types of OCR depending on the tasks they solve: The output of OCR is further used for electronic document editing, and compact data storage and also forms the basis for cognitive computing, machine translation and text-to-speech technologies. That’s why OCR is commonly used for business flow optimization and automation.
Ocr tool meaning manual#
OCR allows you to quickly and automatically digitize a document without the need for manual data entry. Optical character recognition (OCR), also known as text recognition technology, converts any kind of image containing written text into machine-readable text data.
Let’s find out more about what OCR is, how OCR powered with machine learning is different from the original technology, and how it can be used in business. With the growing interest in OCR and Machine Learning, more and more business owners are looking for ways to apply this killing combination to optimize their business processes, and if you are one of them, this article is for you.
