  • EasyLocate Interest Point : New working mode (alternative to EasyLocate Axis Aligned Bounding Box) simplifying the annotation of the dataset and the configuration of the tools when all objects have the same size. A single click is enough to annotate an EasyLocate Interest Point object.
  • EasyGauge : New Polygon Gauge in addition to Point, Line, Rectangle, Circle and Wedge gauges.
  • Deep Learning tools now supporting GPU processing on NVIDIA Jetson.
  • Faster compilation time with simplified C++ headers and reduced calling cost to the Open eVision API.


Segmentation
Segmentation

EasyOCR2 uses an advanced novel algorithm to locate the texts to read in the image. The topology of the text to detect (number of lines, words and characters) can be freely set by the user.


Assisted learning
Assisted learning

When learning from sample images, an interactive tool available in Open eVision Studio is used to identify samples of each character, allow the library to learn them and save the resulting font file.


Neo Licensing System
Neo Licensing System

  • Neo is the new Licensing System of Euresys. It is reliable, state-of-the-art, and is now available to store Open eVision and eGrabber licenses.
  • Neo allows you to choose where to activate your licenses, either on a Neo Dongle or in a Neo Software Container. You buy a license, you decide later.
  • Neo Dongles offer a sturdy hardware and provide the flexibility to be transferred from a computer to another.
  • Neo Software Containers do not need any dedicated hardware, and instead are linked to the computer on which they have been activated.
  • Neo ships with its own, dedicated, Neo License Manager, which comes in two flavours: an intuitive, easy to use, Graphical User Interface and a Command Line Interface that allows for easy automation of Neo licensing procedures.

All Open eVision libraries are now also available for embedded ARM devices.


Character type specification
Character type specification

The character type (letter, digit, symbol, …) of each character can be specified to improve the recognition speed and rate.


Support for TrueType Font (ttf) files
Support for TrueType Font (ttf) files

EasyOCR2 requires training the font to be recognized. This can be done either from sample images or from standard .ttf (True Type Font) files. This makes the recognition flexible, fast and reliable.


Open eVision Studio: Evaluation, prototyping and development tool
Open eVision Studio: Evaluation, prototyping and development tool

Open eVision Studio is the evaluation, prototyping and development tool of Open eVision. Its intuitive graphical user interface allows you to call and immediately see the result of any of eVision's 2D image processing functions. A scripting functionality generates the corresponding code, which can then be copied and pasted into your application.

Open eVision Studio is free (when using Open eVision 2.0 and above) and does not require any license.

Just click on DOWNLOAD OPEN EVISION STUDIO and install Open eVision. Sample images, manuals and sample programs are included.


EasyOCR2 Description

EasyOCR2 is a font-dependent printed character reader. It has been designed to read short texts such as part numbers, serial numbers, expiry dates, manufacturing dates, lot codes, … printed on labels or directly on parts.


Full support for text rotation (360 degrees)

Pre trained classifiers
Pre trained classifiers

EasyOCR2 now supports Optical Character Recognition powered by deep learning technologies. It comes with two pre-trained character classifiers that work out of the box and do not require any training! Read short texts such as part numbers, serial numbers or date codes printed using standard industrial fonts or the OCR-A font. Both classifiers support uppercase letters, numbers and the most common punctuation marks. No GPU is required. The OCR2Demo sample program as well as Open eVision Studio have been updated to support the new functionality.
