I'm designing an LPR application for academic purpose, and one of the steps in the detection step is to fill the holes in a dilated edge detected grayscale image, I would like to know if there's a C# code that could do that

  • You might want to look at [AForge.NET Framework](http://www.aforgenet.com/framework/) which is entirely written in C# and is available on [NuGet](https://www.nuget.org/packages?q=aforge.net). The framework contains classes for edge detection, hole filling and much more. – Anders Gustafsson Feb 10 '14 at 12:50

I suggest you to use opencv library, which works well under C# also that you may be know already about. you find functions to - detect outer contours - detect inner contours, and make some morphological processes that help you in filling holes.
