As i am going to develope an Optical Character Recognition software therefore i want typical image processing functions like...

1)Fourier Transforms

2)Histogram Equalization

3)Edge Detection

4)Conversion to Grayscale Image etc

I don't think anything in .NET will do the first 3 items for you. The grayscale could be done relatively simply if you want a simple method (just read each pixel and convert to grayscale - slow, but it would work).

 

If you want more indepth imaging functions and don't want to write them yourself you'll probably want to buy a library. ULead used to offer a package but I've never used it. I'm sure there are others. You might also look for an ActiveX-based library in case you can't find a .NET version.

At the moment I am wrapping a (imaging) C-Library in MC++ for using it in .NET applications. However, this library is copyright protected and I think too expensive for regular use.

But what you could do is to find another c or c++ library and wrap it in a __gc class. That's pretty easy but time consumig if there are many functions ... and then you can use the funtionality in any .NET application. I have heard about a free library that's still under development http://www.itk.org - maybe there you find what you need.

Well I think u should write it yourself cauze it's kindda hard to find free library for image processing. There are many available in the market VicWin, MIL(Matrox Imaging Library) etc. Email me if u have some problems with algorithms. will try to help(I'm not a pro) in anyway i can.
