OMR SDK Libraries
LEADTOOLS provides fast and accurate Optical Mark Recognition SDK libraries for .NET 6+, .NET Framework, .NET MAUI, Xamarin, UWP, C#, VB, C/C++, Java, Objective-C, Swift, and HTML / JavaScript developers. Leverage the LEADTOOLS OMR toolkit to rapidly develop robust, high-performance recognition applications that detect whether boxes are checked and bubbles are filled within surveys and tests, saving time and money over manual data entry and inspection.
A-to-Z OMR Libraries
The LEADTOOLS OMR libraries automatically detect and process large numbers of test sheets and surveys with hundreds of bubbles. The OMR APIs provide AI-powered components that automatically detect structured and loosely structured bubble layouts that help end-users to rapidly define master form templates by clicking and dragging over large multiple-choice bubble groups.
No Specialized Processing Equipment Necessary
LEADTOOLS OMR libraries do not restrict your end-users to using specific OMR form designs that require specialized equipment to be processed. This is important so that you are not locked into a vendor specific form.
OMR Statistics and Comparison
LEADTOOLS OMR libraries evaluate forms and surveys to calculate grades for tests and detailed statistics for surveys. LEADTOOLS OMR API automatically compares marked tests against an answer key to calculate grades.
Unbeatable Speed and Reliability
Apryse is continuously optimizing LEADTOOLS OMR libraries to ensure that they are as fast and reliable as possible. This makes the API perfect for applications that range from unattended large volume document batch processing to converting single and multipage documents with manual review. Because LEADTOOLS has libraries for multiple platforms, these applications can run on mobile devices, workstations, servers, and in the cloud. LEADTOOLS makes the most of the hardware made available to it.
Cross-Platform OMR Libraries
There is practically no limitation to where you can deploy a solution that uses LEADTOOLS OMR libraries. No matter if you need an OMR solution for desktops, servers, or mobile devices running Windows, Linux, macOS, iOS, Android, or even in a web browser, LEADTOOLS has you covered. The libraries even provide specialized image processing to handle common deformations, such as 3D perspective skew and keystone effect, that occur snapping pics on mobile devices and digital cameras.
Mixed Zone Recognition
Recognizing that automation and efficiency are at the forefront for developers building OCR solutions, LEADTOOLS has mixed mode AutoZone capabilities to extract text from images that contain a mix of machine-printed text, handwritten text, MICR, MRZ, OMR, graphics, and table zones. LEADTOOLS automatically detects and recognizes everything. This powerful combination of OCR, ICR, and other advanced recognition technologies is critical for companies that need to quickly and accurately process various form types regardless of how the data is formatted.
Other Industry-Leading Recognition Libraries
For the past 27 years, LEADTOOLS recognition libraries have been used by thousand of developers and millions of end-users throughout the world. The patented machine learning algorithms that drive these engines bring unparalleled accuracy, speed, and reliability to all of the LEADTOOLS recognition libraries, including the OMR API library.
