I have a Microsoft LifeCam and I want to Capture image using C# and use the image inside my application.
I have checked A previously asked question in SO but the link provided in first answer to OpenCV looks to be invalid ( I get "FORBIDDEN" response ).
I want to know if there is any Sample that I can use to learn and capture Image from LifeCam? And also I need the dll (s) for this.
Does anyone have any experience in this case?
Thanks to Sascha, ESCAPI Solution really helped, I used the ESCAPI.dll along with the C# wrapper to translate it to C# and it all went well.

I have two screenshots. One is expected, another one is actual. I was looking for a good way to compare those screenshots using C# for my automated selenium tests. I found a few decisions to do that in java but C# doesn't provide a lot. I'd appreciate any help
You can use ImageMagick a 3rd party application. It supports command line calls to do image comparison. The following link discusses how to use the command line call:

You can also use the nuget package for ImageMagick. This would allow you to embed C# calls to the nuget library in your .NET application. The following stack overflow answer discusses it:

Both of these links assumes that you have been able to do the image capture part already.
You can do this by sikuli with selenium web driver
I am building a softwere that can decode and encode using Wpf and c#, and I want to do that using, FFmpeg libary. I saw the ffmpeg autogen warpper but I couldn't find any documantion for its function.
Can someone please find me one? Or better, give me better warrper.
I already tried FFMpegCore, its working but very slow. For Exaple it takes 20 seconds to decode a specific frame.(And i have monstruos computer)
If will be happy if ou could give me better warpper, or a guide for ffmpeg.autogen.
Thanks in advance.
FFmpeg framework is powerful, from the other hand is so large which makes it complex. If you want to mess with it, you will have to read a lot before start coding. I would recommend starting with the original documentation and examples that can be found here :-
FFmpeg Libraries Documentation
FFmpeg C Examples
And then move to some open source examples -based on what you want- coded in C# with FFmpeg.Autogen bindings.
You can check my recent FFmpeg.cs implementation that is for decoding (audio/video/subtitle frames).
FFmpeg.Autogen C# Example
I've been building my own media player to cater for my needs and I'm using
Flyleaf:https://github.com/SuRGeoNix/Flyleaf which is based on FFMPEG. There are samples in the code to get you started.
I've also seen this: FFME: https://github.com/unosquare/ffmediaelement
I am working on a project C# and I have to write a code that detects all the objects inside an image (if not all as much as possible).
is there any good API to do that in .NET?
I tried Cognitive Services but they do not give me the detected objects. only what inside the photo.
thank you.
Try the AForge.NET Framework:
They have some neat examples too.

I would like to get the text string saved on an NFC tag in Unity. I'm not experienced with developing for Android, it seems there was already success doing this but it seems to involve extensive use of the Android SDK and Eclipse, neither I'm familiar with.
I found also this thread though the source code is incomplete and I'm not sure how to declare the variables used in this if statement: http://forum.unity3d.com/threads/162834-AndroidJavaObject-as-array-for-NFC-access?p=1115826&posted=1#post1115826
Any usings that I need to import in order to use this snippet and the "var" type variable mentioned in the first post?
OP hasn't been answering all the other questions for over a year now.
I hoped someone here might have an answer for NFC in general.
Pablo from Twinsprite has put a full working example project on GitHub
And he has written a very detailed blog-post about how to create the required plugin yourself.
Works great for me!
For someone else reading in the future, they have an updated link:

I am working with this right now and I will keep you updated
first excuse me for the bad english, then i wanna ask you a piece of advice to solve this problem. I'm trying to use zxing C# port.
I tried then to parse this image:
bar code http://img168.imageshack.us/img168/2633/0003gby.jpg
at zxing.org which recognized it.
The little program I wrote, instead produced a ReaderException.
Any ideas, or anybody who wrote a piece of code which does the job?
I realize this is a bit old, but I've just tried using ZXing's C# port for the first time, and I've found that I have to use the TRY_HARDER DecodeHintType to get the barcode to read.
In the code, it looks like it's expecting the image provided to be a region around the barcode itself, so it starts looking in the middle. Setting the TRY_HARDER flag makes it search the entire page.
