How OCR software works
OCR software recognizes text based solely on its optical properties. This makes it idea for working with scanned text, which is nothing more than an image file until OCR software is applied to it. OCR software identifies the shapes of text characters on a solid background, and compares these shapes to information in its memory, in order to determine which characters the shapes match. Using this technology, OCR pieces together characters and words with remarkable speed, making the text in scanned images fully accessible to the computer.
OCR and text extraction
OCR is an important first step in any kind of text extraction. Text extraction refers to special programs that take text from scanned documents and compile it in a spreadsheet that is organized according to the needs of the user. However, before text can be extracted from a scanned image, the text needs to become machine-readable. For this, OCR software is necessary. Text extraction tools usually contain an OCR engine, so the process does not need to be broken up into multiple steps. In a single convenient process, a batch of forms can be converted into an organized database of information.
How to apply OCR text extraction from PDF files
OCR text extraction is becoming increasingly widely used in offices around the world to eliminate data entry. Instead of entering data from piles of documents, you can just scan the documents and automate data entry entirely. The most important things to keep in mind are the structure of your documents, which determines your ability to extract text effectively, and the accuracy of the software itself. Research the latest OCR tools to find one that is designed for documents like the ones that you process, and then just follow the instructions to set up the software and get started with text extraction.
