Utility of OCR
OCR has achieved iconic status in the world of document processing, digitization and conversion as well as storage. OCR refers to Optical Character Recognition, and as the name implies, it is concerned with the conversion of various forms of text, be in typed of handwritten into acceptable digital formats. Take for instance a case where someone would want to copy excerpts of a book and compile it into a separate document. One way of this, albeit manual and effort intensive, would be to type out the portions that are required as an excerpt. The smarter way would be to put the document through an OCR scanner and get the required portions in electronic form instantly. OCR software is also useful in in administering multiple choice exams, reading bar codes for retail applications and so many more commercial, academic, administrative and personal applications. It is really quite understandable that OCE has become so popular in the heavily networked world that we live in.
Free OCR Software
There are a lot of OCR software firms that offer free OCR software online, primarily as demo or trial versions. These free versions can be used by potential customers who would like to try out and evaluate the functionality as well as salient features of the OCR software. Once the software is tried out, customers can order the fully paid for and completely loaded software in order to meet their specific OCR needs. There could be differences in various software packages and the functionality that goes with it, leading to the need for proper assessment and evaluation of the software, also keeping in mind cost considerations such that one gets the best value for money.
Limitations of Free OCR Software
Free trial versions of OCR software are meant to just provide a preview of the kind of functionality that one can expect from it. For operations that involve large files as well as rather unwieldy formats. The free trial version would not be appropriate as it would not be able to meet the accuracy standards. For OCR, close to 100% accuracy would be required, which are standards that cannot be met by trial version.
