I have some images in png format, I am wondering whether there are .net library to process images?
You may take a look at GDI+ (System.Drawing namespace) or WIC, both have managed wrappers built into the .NET framework. For example here's an interesting article comparing both methods for resizing an image. Of course depending on your specific requirements and what exactly do you mean by processing images there might be also third party libraries.
The System.Drawing.Bitmap class supports BMP, GIF, EXIF, JPG, PNG, and TIFF. You can at least display your PNGs using that.
Also I found a library AForge which is used in an image processing on codeplex.

I need to transcode video streams using C#. The streams come in a variety of formats, like MP4, H264, H263, VP8. Is there any library for c# that can transcode a MemoryStream?
There is a ffmpeg-sharp library
ffmpeg-sharp is a wrapper library over the FFmpeg multimedia suite
that provides easy to use wrappers for use in CIL products under both
Mono and .NET
Also look at SharpFFmpeg
SharpFFmpeg is a C# binding of ffmpeg. The goal of SharpFFmpeg is to
provide the facility that allows .NET developers to easily create
audio and video applications.
And MeWiG - MEncoder GUI for Windows
MeWiG is a Windows Frontend to the MEncoder (part of MPlayer) using
the .NET Framework.You should be able to crop, scale, deinterlace, etc
and finally convert almost any digital video-source, without the need
for commandline-options.

Currently, I am looking for a (commercial or free) .NET/C# image processing library for a WinForms project to apply customizable effects like Instagram or Microsoft Office Word does, e.g.:
I found plenty of image libraries like:
ImageMagick
Lead Tools
Free Image
DotImage
...
Unfortunately, all these libraries seem to provide a rather low-level way of manipulating images. When it comes to high-level effects like borders, rotation, vintage filters like Instagram, etc., I found zero libraries.
(Ironically, for JavaScript, there are quite a few libraries out there)
Maybe there is no market for such a library, still I would love to have this function in my application without doing everything on my own.
Therefore my question is:
Is there a .NET library available to have a customizable and extendable way of applying various high-level filters to images?

What is good book to read on about image processing in C#, and image processing overall.
Image will be taken from a camera and will be searched for certain objects, changes, etc.
If you're just wanting to to "basic" image manipulation functions, like color adjustments or things like that then you should probably just brush up on basic math and bit manipulation, you'd be surprised what you can accomplish with a few simple tricks (like in this post and this article).
However, if you're serious about image processing I would recommend Algorithms for Image Processing and Computer Vision, the source is in C, but that doesn't change the underlying concepts.

I am using C# 2.0 and developing an application to convert a PDF file into HTML, Word, Excel and Image (GIF,JPEG,PNG,TIFF). Is there any free library / class available for that?
The iTextSharp library allows you to manipulate PDF files. You should be able to build what you need from it.
I know you want a free library, but a good library I've used is Windward .NET reporting engine. It is very expensive, though.
Solid Framework does a good job with PDF files. Not free though. I have tried iTextSharp and PDFBox and I can say PDFBox is rather easy if you just need the text content.

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.
