## What is eVision

**eVision** is a set of powerful image processing tools developed for computer vision applications. They cover most state-of-the-art techniques in digital image processing, from classical algorithms to advanced solutions ready-made for specific tasks.

**eVision** provides the following tools:

* [**Basic Types and Operations**](../using/basic_operations/index.html.md): fundamental objects, types, classes and functions used in all components.
* [**General Purpose Tools**](../using/general_purpose/index.html.md):  process and optimize your images.
* [**Matching and Measurement Tools**](../using/matching_and_measurement/index.html.md): find and measure objects in your images.
* [**Text and Code Reading Tools**](../using/text_and_code_reading/index.html.md): decode codes or read texts.
* [**Deep Learning Inspection Tools**](../using/deep_learning/index.html.md): inspect images with deep learning technology.
* [**3D Processing Tools**](../using/3d_processing/index.html.md): solve computer vision problems using 3D.
* [**Applicative Processing Tools**](../using/applicative_processing/index.html.md): solve various known computer vision problems.

Many of the available tools are designed to be self-consistent and easy to use. Nevertheless, for more advanced uses, you should find everything you need to build you own workflow by combining the numerous building blocks provided.

**eVision** is made of a set of C++, .NET and Python classes ready for integration in your application. The tools are in no way a closed solution and do require to be integrated in your own application, leaving you all the freedom to deal with all other aspects of the automation not related to image processing.

## The Studio Applications

**eVision Studio** and **Deep Learning Studio** are software applications that allow you to test all **eVision** libraries and tools. They speed up and automate the creation of a solution for your vision problem.

You can test the functions to find appropriate parameter values, and generate the code of your operations to copy and paste into your own applications.

The following Studio applications are provided:

| ![](assets/images/home/new_studio.webp)           | **eVision Studio** to evaluate and prototype your application.                 | [Getting Started](evision_studio/index.html.md)   |
|---------------------------------------------------|--------------------------------------------------------------------------------|------------------------------------------------------------------|
| ![](assets/images/home/studio_deep_learning.webp) | **Deep Learning Studio** to train and evaluate your deep learning application. | [Getting Started](../using/deep_learning/deep_learning_studio.html.md)   |

The Studio applications are available in the [download area](https://www.euresys.com/en/Support/Download-area) and do not require any license.

## The Samples

**eVision** provides various samples in its installation packages:

* **sample programs** showing how to use **eVision** libraries with a particular IDE.
* **demo applications** showing how to combine **eVision** functions and libraries in a variety of combinations and applications (only available on Windows).
* **sample images** to use with these.

The samples are installed in the following folders:

* Under Windows
  * `C:\Users\Public\Documents\Allied Vision\eVision 26.10\Sample Programs`
  * `C:\Users\Public\Documents\Allied Vision\eVision 26.10\Demo Applications`
  * `C:\Users\Public\Documents\Allied Vision\eVision 26.10\Sample Images`
* Under Linux
  * `/opt/alliedvision/eVision_26_10/Sample Programs`
  * `/opt/alliedvision/eVision_26_10/Sample Images`

## Deprecation Warnings in eVision

* The **eVision** tools and libraries are an evolving product, and regular improvements are performed.
  * Sometimes, to implement these improvements, the API of a library must evolve too.
  * In this case, the old API is preserved alongside the new one, but is marked as deprecated, indicating that it might be removed in the future.
* The deprecations are tagged within the **eVision** headers using the `[[deprecated]]` attribute (`[Obsolete]` for .NET).
  * **eVision** raises warnings if you use these deprecated methods in your code.
  * You can safely ignore these warnings as they only indicate that you should update these API features because, in the future, they might be removed.
