I got an opencv [c++] function to perform certain image processing algorithms. Now i want to call that function from c#, i am not allowed to use any wrappers or emgu cv. is there any other way to achieve this ?

thanks

Small remark. We suggest not to use hashtags in the tags of your topic. They generate a lot of double tags, rendering the search and filter options useless. Keep this in mind at your next post, adjusted it for you now.

And this could be the solution to your problem, an approach called PInvoke.

You can create managed wrapper with managed C++ and call it from C#.

That's how I do it, too. The trickiest thing is to convert images to cv::Mat's and the other way round. Here's how you can do the latter one: http://answers.opencv.org/question/14183/having-trouble-with-using-mat-image-in-picturebox/
