New Handwriting Recognition & Mixed Zone Recognition Libraries in LEADTOOLS Version 21

There is a great and growing need for people and organizations to be able to quickly recognize and extract data from documents, images, and forms that are filled with varying areas of machine printed text, handwriting, graphics, and more (think: almost every type of form you’ve had to fill out and sign). Handwritten text specifically has been historically difficult to recognize due to variations in each and every sample set of handwriting. With LEAD’s continued commitment to advancing OCR technology, our developers set out to create a solution. Version 21 brings a new and improved ICR engine as well as brand new Mixed Mode AutoZone capabilities.

LEAD’s new ICR engine raises the bar for what application developers can create. Able to recognize both handwritten print and cursive text, LEADTOOLS handles handwriting recognition even on low quality or noisy images. It also provides outstanding recognition success rates, comprehensive reports of text results, and full support for the English character set, including uppercase, lowercase, numerals, punctuation, and symbols. Once the text has been extracted, users can output to any searchable-text format such as PDF, PDF/A, DOC, DOCX, XML, XPS, and more.

Adding to this impressive ICR engine, is the new Mixed Mode AutoZone recognition. This combines LEADTOOLS OCR, ICR, and Recognition technologies to automatically analyze and label different zones in order to detect, recognize, and extract information from images and document images that contain a mix of machine-printed text, handwritten text, MICR, MRZ, OMR, graphics, and table zones. Once LEADTOOLS has Auto Zoned the image, the appropriate engine is used to recognize data within each zone, allowing developers to easily create applications that extract everything within an image.

This powerful combination of recognition technologies is critical for companies that need to quickly and accurately process various form types regardless of how the data is formatted. Users will no longer need to manually set the recognition zone type when dealing with a document that has both handwriting and machine printed text, which saves countless hours and reduces errors.
