Here are some questions to ask when purchasing optical character recognition systems: Prices of self-contained OCR systems and those that come bundled with a PC range from $3,500 to $5,500. This does not include the personal computer and screen access equipment. The price for the most popular PC-based OCR systems is about $1,000. A person who is blind or visually impaired can access the scanned text by using adaptive technology devices that magnify the computer screen or provide speech or braille output.Ĭurrent generation OCR systems provide very good accuracy and formatting capabilities at prices that are up to ten times lower than a few years ago. In some OCRs these temporary files can be converted into formats retrievable by commonly used computer software such as word processors, spreadsheets, and databases. Finally, the information is stored in an electronic form. The synthesizer in the OCR system then speaks the recognized text. An OCR system will deduce that the word “tke” at the beginning of a sentence is a mistake and should be read as the word “the.” OCR systems also use a lexicon and apply spell-checking techniques similar to those found in many word processors. The recognition process takes account of the logical structure of the language. OCR software then converts the images into recognized characters and words and creates temporary files containing the text’s characters and page layout. Initially, a printed document is scanned by a camera. There are three essential elements to OCR technology-scanning, recognition, and reading text. For machines and software it is the difference between understanding of the contents of the file and the inability to read it.Optical character recognition (OCR) systems provide persons who are blind or visually impaired with the capacity to scan printed text and then have it spoken in synthetic speech or saved to a computer file. For us, as users, the visible change will be only a different file extension - DWG instead of CGM. File Converter - is a binary code translator compensating for differences in the code or making it a true translation, so that another machine or program understood it. A list of software to perform the conversion you are interested in can be found at the top of this page. To obtain a matched structure of the data, it is necessary to use an appropriate converter. If this is not possible, we can try to independently perform the conversion process from CGM to DWG. After exporting, you can easily perform IMPORT of the data in another application. The effect of the operation of one of the program is automatically the input for another application (some applications provide the possibility to automatically save the work done on the file CGM file to the DWG format - EXPORT data). Export and import of data and a manual conversionĪ data conversion is normally an automated process to some extent. Data included in the CGM file can be converted not only for the requirements of another application, but also for transfering them to another computer system. ![]() Every time, when data is to be forwarded, they must be converted to a readable format for the next application - we are interested in the DWG output format. ![]() What they are interested in is the appropriate form or presentation of data, so that they could decipher its contents.ĭespite the fact that the data are in the final form the strings of ones and zeros, they must be strings ordered in such a way as to be legible for a specific application or platform. The machines see the data in the files in a completely different way. We as end users are primarily interested in the substantive content of the file. Data conversion is a process performed for the requirement of the computer technology. The conversion of the CGM file to DWG file is the process of changing the form of the presentation of the data, and not the data itself.
