Reliable results in challenging scenarios

Text Recognition With Optical Character Recognition

MVTec software offers powerful technologies for text recognition (OCR) based on classical methods and modern deep learning approaches. This enables reliable results even in challenging scenarios, such as tilted text, distorted characters, or markings printed or etched on reflective surfaces and highly textured color backgrounds.

AI-BASED TECHNOLOGY

Deep OCR

MVTec’s Deep OCR follows a holistic, deep learning-based approach. Characters are localized robustly, independent of font or orientation. By automatically grouping characters into words, the recognition rate increases significantly because confusions between similar-looking characters are avoided.

RULE-BASED TECHNOLOGY

Traditional OCR

Our software library includes numerous predefined classifiers for different font types, including dot matrix, semi, and industrial fonts as well as handwritten fonts. They deliver excellent recognition rates without additional training, for example with an error rate of 0.65% on the MNIST dataset.

Tools and assistants simplify the training of custom fonts.

Segmentation & Performance

A key factor for OCR is character segmentation. MVTec combines freely definable regions with powerful blob analysis and comprehensive filtering techniques. This makes it possible to reliably extract characters even from complex backgrounds. A single character is read in less than 0.1 milliseconds.

Typical applications include:

  • Serial numbers and codes on tires or metal parts
  • Dot matrix fonts on complex backgrounds
  • Handwritten digits or custom fonts
  • Label and document recognition with syntactic and dictionary-based autocorrection
