Accord.NET Extensions is an extension framework for Accord.NET and AForge.NET. The framework sets focus on .NET native array as primary imaging object and offers computer-vision algorithms mostly build as extensions. The libraries can be grouped as following:
-
Accord.Extensions.Imaging.Algorithms package
Implements image processing algorithms as .NET array extensions including the Accord.NET algorithms.
<li>
<p>
<b>
<a href="https://www.nuget.org/packages/Accord.Extensions.Imaging.Algorithms.LINE2D/">Accord.Extensions.Imaging.Algorithms.LINE2D package</a>
</b>
<br />
Implements template matching algorithm (~20x faster than conventional sliding window approach).

The best ways to contribute and provide feedback is to try things out, file bugs and propose enhancements. Your opinion is important and will define the future roadmap. If you have any questions, comments or you would like to propose an enhancement please leave the message on Github, or write to: darko.juric2 [at] gmail.com.
If you like the project please star it in order to help to spread the word. That way you will make the framework more significant and in the same time you will motivate me to improve it, so the benefit is mutual.
