I am looking for a C# library to generate and read micro QR codes (example below). It would be great if the llibrary could recognise a micro QR code in an image with other things in it (i.e. isolate and read the QR code.)

There is an open source project called QRCode.
QRCode library is a .NET component that can be used to encode and
decode QRCode.

Did not work very well for me.
Try google codes .net port http://zxingnet.codeplex.com/

I have been using Emgu CV for 2 years to provide Facial Recognition to an open source project already using Kinect API. All the code is in C#.
Now I'd like to also provide Blob Tracking Learning Detection like Predator or CMT and don't know what library to use. I didn't find a Predator implementation in C#. I also didn't find a Blob library build on top of the Kinect SDK.
So should I keep digging into Emgu CV? Or looking for something new? Maybe using Kinect leverage?

I would like to find some information about DVD+-VR with IMAPI2. I guess it is possible to create and burning DVD-VR with IMAPI2 but I can not find examples how to do.
Do you have some idea or some example code?
Thank you very much.

I need to write a c# assembly (DLL) in order to scan documents.
I don't know if I need to use TWAIN or WIA.
Anyone could help me please ?
What are the différences?
What are your advices ?
Is there a c# Library ?
Generally, if your application is to interact with scanners, TWAIN is recommended. While for cameras, WIA offers better support.
So for document scanning solution, I would recommend TWAIN.
TWAIN.H file is a C/C++ header file. If you want to code it to .NET yourself, you can refer to this post to get some resources:
Using TWAIN in .NET - Looking for resources
Or you can use a commercial .NET TWAIN component.

Do you know any opensource libraries for DJVU? I can't find anything useful.
One of the most rated DjVU library is here:
DjVuLibre
However is in C++.
I created an open source Djvu library which is written in C#. It needs to be optimized a bit, but is fully usable. https://github.com/Telavian/DjvuNet
As for open source DjVuLibre mentioned by Steve, you could find some pointers how to use it from .NET here - Creating simple c++.net wrapper. Step-by-step
As for paid libraries - you could look at: Caminova DjVu SDK for .NET Framework. This is not too expensive.

I am looking for any open source/free graph(charting) library in C/C++ or C#. Just like free JfreeChart in java.
Does anyone know it?
I'm a big fan of gnuplot... It's open-source and very versatile.
You can try Microsoft Chart Controls for Microsoft .NET Framework 3.5 for .Net.
Samples are also available.
Take a look at MathGL
DynamicDataDisplay for C# is free and a quite efficient way of charting data. It supports quick pans and zooms.
