Can your camera or smartphone replace a scanner for document capture with OCR? The answer is a resounding YES! TopSoft, Ltd, a leading developer of OCR and image processing software has created an application specifically for OCR data capture with digital cameras and smartphones called TopOCR. TopOCR uses the latest most powerful neural net pattern recognition and digital signal processing techniques for the best possible OCR results from digital cameras. This OCR technology is the result of years of research and development in the United States and Europe. Unlike OCR applications designed for scanners, TopOCR understands that images from digital cameras and smartphones have more variation in image quality. As a result, the OCR processing in TopOCR is more robust and utilizes sophisticated image processing algorithms that the older OCR programs completely lack. After a lot of testing, and feedback from early users, many people feel that OCR document capture based on digital cameras will be the wave of the future.
Understanding Digital Camera OCR
Replacing a scanner with a camera can dramatically improve OCR throughput. It can also allow you to have a portable solution to document capture and OCR on content which normally would be inaccessible. In order to have a high degree of OCR accuracy, it's necessary to understand the limitations of the current version of TopOCR. To give high OCR accuracy, TopOCR requires a minimum of a 3 MegaPixel digital camera. This will allow a user to TIGHTLY frame an 8 1/2\" by 11\" document. TopOCR can handle variable lighting, which ordinarily would give poor OCR results, and small amounts of document skew. Large amounts of skew will generate significantly more errors. Therefore it is essential for the user to learn how to use their camera effectively for the best OCR results. This best way to improve your skill is by practicing, after first reading our tutorial, download TopOCR and you can get started!
Multi-lingual OCR
TopOCR can OCR documents in one of 11 languages they are: English, Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish. You'll get the same great OCR results in any of these languages.
Some Developmental Highlights of TopOCR

The neural net technology used in our product is based on almost 10 years of joint research by a team of university mathematicians. This was used as the foundation for our development team who took over two years to code the basic OCR engine. The development team consisted of members who wrote the:

[li]Image filtering DSP engine [/li][li]Document Layout Analysis routines [/li][li]Line/word/character segmentation routines [/li][li]Character feature extractor [/li][li]Syntactic pattern encoder [/li][li]Fast neural net recognition engine [/li][li]Linguistic and statistical post-processor [/li][li]And the TopOCR application! [/li]

In addition, our efforts were greatly assisted by the QA team, and from volunteers who sent us document samples from all over Europe in more than 20 languages. The aim of our efforts has always been to take OCR to a new unique direction. In our first release, the focus is on using OCR with digital cameras. Even though this is our first release, we think it goes a long way in making it easier to use a digital still camera as a document capture device. Our OCR engine is the newest major OCR engine to enter the market place in over 10 years. Some of the popular OCR engines used today were designed over 20 years ago. Our approach is based on newer more effective technology, and follows its original efficient design structure. As a result, we not only deliver better accuracy on images from digital still cameras, but our application is only 1/10 the size of older generation OCR engines. We intend for TopOCR to continue to evolve and to continue the journey of taking OCR to new frontiers.
