I was wondering whether anyone knew of a good tutorial for Capturing an Image/Video stream from a web camera using C#?
Any suggestion would be a appreciated.
Thanks.
Here's a tutorial for EMGU Camera capture in 7 lines of code.
Setup of the EMGU library is fairly easy to do, and the capturing of the camera is truly that easy.
EmguCV is a good wrapper around the OpenCV API. There's a number of tutorials in the link.
i use AForge.NET.. Look at this sample
Try Microsoft Expression Encoder

I need to implement some code on top of a MetaWebLog API client library. The only thing I am finding on google is broken links from the last decade.
Does anyone know of a library (or code) that implements the MetaWebLog API from a standpoint of a client app?
JoeBlogs is a library that allows easy interaction with Wordpress blogs, and other blogs that support the metaWeblog XML RPC api.
Live Writer Provider Documentation and .Net Example
MetaWebLog To BlogML Converter — you can get the source code and use MetaweblogAPI.cs.
Matlus (http://www.matlus.com/metaweblog-api-c-library/) has an extremely simple to use MetaWeblog system that uses only System.IO.Stream for communication. It was by far the simplest Metaweblog example I could find.

I am looking for an open source tool to help me create mosaic images based on a series of given images. I've been searching the web but couldn't come up with anything web oriented solution.
Do you know any such tools?
Thank you
This might be what you are looking for: http://www.openprocessing.org/sketch/39934
If you download the code and make a new refresh.jpg it should work. The code is written in processing which is very similar to java and can be run as an applet online if the user has java enabled in the browser.
Creating images is normally something you would do on the server side but this might come close to what you are looking for: http://ajaxian.com/archives/mosaic-image-builder-with-ajax
if you just want to show your images in an mosaic way you could use something like masonry: http://masonry.desandro.com/index.html

Need to do a remote image capture from a "prosumer" camera into a C#/.NET app (for capturing pics at a higher resolution and more control than a webcam).
Any advantage for Canon vs. Nikon remote capture SDK's? Is one better supported than another? Looking for a developer perspective before embarking on this one...
I looked at both SDK's when I was picking out cameras. I ended up going with the Canon EOS 50D and their EDSDK. Canon has a wrapper class in their code with all the P/Invoke ready for you to use. That was the primary reason I used it. Some of the P/Invoke types are a little odd. I had issues with figuring out some object reference types needed to be casted to some internal structures... Lot's of trial and error. Eventually I got it to work, and it works well. I have live image capture and static image capture working for it.
I'm sorry I cannot speak for Nikon's SDK. I just chose Canon's because the P/Invoke was already there. The downside to EDSDK is it only works with the EOS line.
Here is some more information.

I've found a similar project here: Sentiment analysis for Twitter in Python . However, I'm working on C# and need to use a naive Bayesian Classifier that is open source in the same language. Unless someone can shed light on how I can utilize a python Bayesian Classifier to achieve the same goals. Any ideas?
I successfully used the code from this CodeProject article in a project a few years ago and it's still working beautifully with ~99% accuracy.
If you don't strictly need naive Bayes, I would suggest libshogun. It has a huge number of high-quality classifiers, and it apparently has been successfully built for win32 on cygwin. After that's built you can just p/invoke to the DLLs from C#. I think you will find it difficult to find a classifier library written in C# due to the often performance-heavy nature of classification, so your best bet is to call a native library such as this.
This might be something to look at:

what are the best tools for c# to do image processing? i am a beginner and want to learn the basics
Try getting started with this:
http://code.google.com/p/aforge/
(Source: Are there any OK image recognition libraries for .NET?)
Once you learn the basics, you can try writing your own.
Try Emgu CV, it is the wrapper of opencv in .net. And you can get more information about it from :
http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=opencv+c%23
Also check the Image Processing Lab sample in C#, which uses AForge.NET library.
