I've already checked out EmguCV (built off of OpenCV). EmguCV is relatively slow. Is there any other good open source computer vision ASP.NET (using C#)? I'm primarily interested in object detection and facial recognition. I want to be able to recognize common objects (ex. gallon of milk, computer screen, keys, etc). Then identify where they are on the image. It needs to run on Visual Studio 2013. The software would have to be free.
