Released on August 1, 2018, Open eVision is a robust software suite developed by Euresys, designed specifically for image processing and analysis tasks. This open-source solution offers developers an extensive collection of libraries that can be seamlessly integrated into C++, .NET, or ActiveX applications. The toolkit includes specialized modules for optical character recognition (OCR), barcode reading, and mark inspection technologies like character printing verification.

Key Features of Open eVision 2.5

The latest version introduces two significant enhancements:

  1. Improved EasyOCR2: This module has been optimized to improve OCR accuracy and performance.
  2. EasyDeepLearning Beta Version: A new beta feature enabling developers to leverage deep learning algorithms for advanced image analysis tasks.

Included Libraries

Open eVision encompasses a wide range of libraries tailored for various imaging needs:

  • EasyBarCode: Supports 1D/2D barcode recognition and decoding.
  • EasyImage: Provides tools for basic image manipulation and preprocessing.
  • EasyGauge: Enables precise measurement and calibration tasks, including sub-pixel accuracy.
  • EasyMatch: Offers functions for comparing and matching images or objects.
  • EasyObject: Simplifies object detection and segmentation processes.
  • EasyColor: Includes color analysis tools for quality control applications.
  • EasyFind: Helps locate specific patterns or features within images.
  • EasyOCR: Handles optical character recognition tasks with improved accuracy.
  • EasyMatrixCode: Specifically designed for decoding matrix-based codes (e.g., QR codes).
  • EasyQRCode: A dedicated module for QR code detection and decoding.
  • EasyOCV: Integrates OpenCV functionalities for advanced computer vision tasks.
  • EasyDeepLearning: Provides experimental support for deep learning models in image analysis workflows.

Licensing Options

Open eVision’s programming interface is completely free, subject to the terms of use outlined by Euresys. However, for full functionality and deployment, developers can opt for two licensing variations:

  1. Dongle-Based Licenses: These licenses are transferable between PCs but require activation codes stored on a physical dongle device.
  2. Software-Based Licenses: These are tied to specific PC activations and managed online without the need for external hardware keys.
