I am working on image processing. I need to develop an OCR tool using Matlab. Is there any methodology for developing an OCR tool, creating a DLL, and using it in .Net applications. If so, how can I do this?
You can try the MathWorks website. It looks like they have examples of creating mex files and using them in a .NET application. See Creating and Debugging Mex with Visual Studio 2010 and Matlab 2009b
Here 's an example that shows 3 different ways to integrate matlab with C #
you need to use Matlab Builder NE for such things. you can compile any matlab function loading Dll into .net as a class with a function. for this you need to use the Matlab Compiler Runtime - the MCR of the same version as the Matlab that you used with Builder NE.
