OMR SDK: Automatic Template & Form Recognition

Optical mark reader software (OMR software) is designed to scan and process filled-out forms, surveys, checkboxes, etc. quickly and accurately.

The GdPicture.NET forms processing engine provides an anchoring mechanism (also known as template recognition) and Optical Mark Recognition (OMR) features.

The anchoring mechanism can help to align the area to be processed by filters, OMR, OCR, or barcode recognition.

Trusted since 15+ years, by 3000+ and Fortune500 companies, and 10K+ developers.

OMR And Template Recognition Extension For GdPicture.NET SDK

Optical Mark Reader Software, Uses and Examples

If several documents are scanned of the same form, and the scanning orientation or quality is not guaranteed, the GdPicture Anchoring System can be used to specify the orientation of each document and the translation made to each document from the one where the user selected their Areas (surrounding rectangles).

OMR (Optical Mark Recognition) helps to detect the content of a checkbox, fill-in-area , multiple choice examination form, or any area where highlighting is required to indicate a certain choice.

FAQs

Yes. Our OMR technology includes an anchoring mechanism, also known as template recognition, to detect and correct misalignments or skewing in scanned forms. This feature ensures that the areas designated for mark detection are accurately aligned, enhancing the precision of data extraction.

Yes, our SDK supports multiple form templates and can automatically recognize and adapt to different layouts. This capability allows for the processing of diverse forms without requiring manual adjustments for each template.

For optimal accuracy, it’s recommended to scan forms at a resolution of 200-300 DPI (dots per inch). High-resolution images ensure that marks are clearly distinguishable, reducing the likelihood of misinterpretation during processing

Our SDK utilizes advanced algorithms to analyze the density and shape of marks within designated areas. By setting threshold levels, the software can distinguish between deliberate marks (such as filled checkboxes) and random artifacts (like stray dots or specks), ensuring accurate data capture

Yes, our SDKs has integration capabilities with various data management systems, such as databases, learning management systems (LMS), and customer relationship management (CRM) platforms. This integration facilitates seamless data transfer and streamlines workflows, enhancing overall operational efficiency

OMR software is utilized in various sectors for tasks such as grading exams in educational institutions, conducting surveys and assessments in market research, processing ballots, managing data collection in healthcare settings, etc. Its ability to efficiently process large volumes of data makes it a valuable tool across these diverse applications.
