The open source OMR library has provided complete support for recognizing and extracting data from scanned images and documents. It simplifies the process of recognizing and extracting data from scanned documents in Java applications. It precisely captures and interprets data from marked areas on paper forms, ensuring minimal errors in the extraction process. The library allows tailoring the OMR processing to specific requirements through configurable settings. Software developers have the flexibility to adjust parameters such as sensitivity and recognition thresholds, allowing for fine-tuning based on the characteristics of the input documents. The following example shows how to Load the scanned document and extract data from it via Java API.
How to Load & Extract Data from Scanned Document & Forms uinsg Java API?
OMRConfiguration omrConfig = new OMRConfiguration();
omrConfig.setSensitivity(0.8); // Adjust sensitivity based on your requirements
// Set other configuration parameters as needed
OMRSheet omrSheet = new OMRSheet("path/to/scanned-document.png");
// Perform Recognition
OMRResult omrResult = omrSheet.process(omrConfig);
Map extractedData = omrResult.getData();
omrConfig.setSensitivity(0.85); // Adjusted sensitivity based on evaluation
// Refine other configuration parameters as needed
try {
// OMR processing code
} catch (OMRException e) {
// Handle OMR-related exceptions
e.printStackTrace();
}
