OCR Vs. OCR?
Optical Character Recognition software have come a long way for accurate recognition of printed characters. All OCR software basically work by taking the document input from imaging devices like scanners, processing it using digital image processing algorithms, and saving the extracted text into a text file. The market has a number of OCR software and it might get tough deciding which one is the best solution for your home needs, SME needs, or high volume needs. While most of the software offer a number of advanced and extra features, the basis of good OCR still remains accuracy. Without accuracy, recognizing erroneous characters doesn't make sense. However, with the basic measure of accuracy in place, different needs require different demands.
Critical Features in OCR Software
One of the major demands in high volume OCR processing is the need for speed. Along with the speed, it is essential for the OCR software to maintain accuracy. It would be useless to support high speed when scanning, for example, volumes of medical records for archival, with just a single percent of reduced accuracy. The results would be disastrous! Another feature, when combining speed and accuracy is the support for multiple-engine voting technology. This technology makes use of multiple engines to extract characters from the page using different algorithms. The engines then use the character with the highest match-percentage.
An Overall Picture
The need for speed and accuracy add another dimension to OCR - accurate page layout reconstruction. Page layout reconstruction is another attribute to look for in an OCR solution, even for home use. Good OCR software keep the formatting of the digitized page as accurate as the original. This allows pages with images, tables and columns to remain accurate when digitized while maintaining the authenticity of the page. Advanced features of OCR software include support for OCR scanning in multiple languages. The languages supported by the OCR solutions can easily cross the mark of 100. Along with western languages, Asian languages like Chinese, Japanese, and Korean, along with their varying scripts are supported. European languages including Portuguese, Spanish, Dutch, and Norwegian are also supported. The best value OCR software will finally have a good user interface and technical support.
