Data and information is stored in files. The files are classified into various file formats. Data can also be in the form of images. The images can contain text patterns in them. This text is not visible to the normal document reader. Character recognition is the technique by which this text is extracted from the document and made visible to the document reader. Optical Character Recognition is the basic technique used for character recognition. This OCR may be implemented in your document reader by downloading OCR software. This software is available as an extension of the original document reader.
The OCR software will look for the text patterns in the document. The patterns got from the document are matched with predefined text templates in the OCR software database. If the text pattern in the document matches the text template, then a text layer is embedded in the document. The downloaded OCR software inserts this text layer to get embedded into the document. The downloaded OCR software can then extract the text which has been embedded. The text can then be used for searching the content of the document by keyword searches.

This will enable document readers to open OCR embedded files using downloaded OCR software. OCR software is available as a freeware download from World Wide Web. Some downloadable OCR software are commercial software which requires a fee to download and install. The accuracy of the freeware OCR software may not be very high. They are useful if text have to be extracted from files whose text is in the same font or type. Commercial OCR software has an accuracy of nearly 99 percent. They can also support many fonts and can extract text from low quality images. There are also trial OCR softwares which can be used to get a feel of the product. It helps in the user making a choice for downloading OCR software. OCR softwares are becoming a welcome addition to most document readers since it adds functionality to it.
