.NET API to Perform OMR

Nuget

It is a standalone on-premise API that helps in recognizing the human-marked data from images of scanned documents, surveys, questionnaires, quizzes, and examination papers.

Aspose.OMR for .NET not only acts as an Optical Mark Recognition engine. It also provides a handy graphical control that can be used for manual tuning of the threshold and markup to see changes in real-time.

Why Download Aspose.OMR for .NET?

Aspose.OMR for .NET adds optical mark recognition (OMR) functionality to your C#, VB.NET, and ASP.NET applications. With it, you can design, render and recognize all types of hand-filled forms: answer sheets, examination papers, surveys, questionnaires, ballots, applications, and many more.

No specialized equipment, consumables and third-party software required. Use your office copier or even a smartphone camera instead of an expensive OMR scanner. Respondents can fill out your forms with a pen, pencil or marker and use any type of marks - artificial intelligence and advanced accuracy calibration ensure reliable results. You can even recognize rotated and skewed images.

Aspose.OMR for .NET can recognize any file you get from a scanner or camera: PDF, JPEG, PNG, TIFF, GIF, and BMP. Recognition results are returned in the most popular data storage formats (JSON, XML and CSV) that can be imported into any popular database, CRM or analysis system.

Aspose.OMR for .NET supports QR codes and barcodes recognition.

Aspose.OMR for .NET offers a flexible markup language for designing OMR forms of any layout and complexity; you can even add QR codes, barcodes and images without using third-party libraries. All popular paper sizes as well as a number of non-standard ones are supported. Forms are saved in multiple file formats, intelligently selected based on the provided extension: PDF, JPEG, PNG, TIFF, GIF, and BMP.

Aspose.OMR for .NET is written in C#, has managed code, and supports both x86 and x64 systems.

OMR API Features

Recognition of scanned images and photos.
Ability to process rotated and perspective (side viewed) images.
Recognize data from tests, exams, questionnaires, surveys, etc.
High accuracy rate & ability to export the results in CSV format.

Aspose.Total Aspose.Total for .NET is the most complete package of all .NET file format APIs offered by Aspose. It empowers developers to create, edit, render, print and convert between a wide range of popular document formats within any .NET, C#, ASP.NET and VB.NET applications.	230.3K
Aspose.OMR.Handwriting This extension to Aspose.OMR for .NET adds support for handwritten text input to machine-readable OMR forms. Free-form text text recognition allows to create more dynamic and adaptive forms that can capture a wide range of responses without the need for an exhaustive list of predefined answers. While the handwritten text recognition might not be as accurate as standard optical mark recognition, it is more intuitive, user-friendly, and versatile in a number of applications: - Creating more compact and space-efficient forms, making efficient use of limited page space. - Rapidly creating surveys and quizzes without the need for extensive categorization of information into predefined choices. - Appealing to a broader audience, by allowing respondents to write their answers rather than selecting close-ended options. - Automatically digitizing free-form responses into machine-readable text without the need for additional OCR libraries. Important: at the moment, the library only supports Latin letters (A-Z) and Western Arabic numerals (0-9). Changelog: - Added a new element that allows users to enter handwritten text in a free-form manner.
