In this blog post, you will explore document scanning in Java. Whether you’re building a document management system, a mobile app, or an OCR (Optical Character Recognition), OMR (Optical Mark Recognition) application, this guide will provide you with the necessary information to implement document scanning using Java.
Java Document Scanning APIs
Scanning documents in Java provides a seamless way to convert physical documents into digital formats. It offers numerous benefits, including improved document management, easier sharing and storage, enhanced search capabilities, and reduced paper clutter. Java’s cross-platform compatibility and support make it an excellent choice for implementing document scanning functionality.
OCR Document Scanning in Java
OCR is a technology that enables computers to recognize and extract text from images or scanned documents. Aspose.OCR for Java allows you to incorporate OCR functionality into your Java applications, making it easier to extract text from various sources and use it in your programs.
Moreover, it has language support for 27 Latin and Cyrillic scripts, as well as Chinese. The OCR API is capable of recognizing various types of inputs, such as scanned images, smartphone photos, screenshots, specific areas of images, and scanned PDFs.
Below is a list of some important features of Aspose.OCR related to document scanning:
- Text Extraction: Recognize and extract text from images, scanned files, or PDF documents.
- Language Support: Supports multiple languages to extract text in different languages, such as English, Spanish, French, German, and more.
- Advanced OCR Algorithms: Utilizes advanced OCR algorithms to provide accurate and reliable text extraction.
- Pre-processing Options: Apply image filters, such as noise removal, skew correction, etc. to improve the quality of the input image.
- Easy Integration: It is designed to be easy to integrate into your Java applications.

OMR Document Scanning in Java
Extracting and collecting data from paper-based forms, surveys, and assessments can be a time-consuming and error-prone task. You can simplify the process to extract information from scanned documents using Aspose.OMR for Java.
Aspose.OMR for Java can be used to create custom OMR templates defining the structure and layout of the OMR sheets. Similarly, it contains flexible options for exporting the extracted data. You can save the data in various formats, including CSV, XML, JSON, and more, making it compatible with different systems and applications.
Below are some of the document-scanning characteristics of Aspose.OMR for Java:
- Mark Recognition: The ability to accurately detect and recognize marks made on forms, such as checkboxes, bubbles, or shaded regions.
- Template Creation: Create customizable templates defining the outlook of the forms, including the placement of questions, answer choices, and other elements.
- Accuracy and Validation: Algorithms and mechanisms to ensure high accuracy in mark detection and recognition.
- Scanned Image Corrections: Ability to process rotated and perspective (side viewed) images.
