Open eVision Libraries
Open eVision is a suite of reliable, powerful and flexible software tools for image processing and analysis.
Several libraries cover applications such as image filtering and enhancement, code reading, deep learning, classification, 3D vision, pattern matching, alignment, blob analysis, spot detection and metrology. The libraries are split into 4 groups: Deep Learning, Inspection, 3D and ID/OCR/Code Reader
Open eVision contains a set of 64-bit libraries for C++ and .NET (C#, VB.NET, C++/CLI) under Windows (x86-64) and Linux (x86-64 and ARMv8-A).

Various options for licensing
Open eVision dongle-based licenses: Dongle-based licenses offer the flexibility to be transferred from a PC to another. To purchase a dongle-based license, select one of the Euresys dongles (USB or Parallel) plus the license(s) to be stored on this dongle. Licenses are delivered as activation codes, which are stored on the dongles.
Open eVision software-based licenses: Software-based licenses do not require any dongle, they are linked to the PC on which they have been activated. Licenses are delivered as activation codes and can be managed online.
Open eVision Bundles
Open eVision libraries can be purchased individually or in cost saving bundles. No development license is required.
