Shape Recognition in UWP App

I am using Unity for the first time (although I have been using Visual Studio for many years), so I am unsure exactly how to get my Project set up (for example, references). I am looking to find the colored squares in a 5x5 grid (which comes from the device's camera). I am able to get the image (currently a SoftwareBitmap, although it can, of course, be converted to another type if necessary), but I was hoping Unity would have some APIs that could be used in my UWP .NET code to help me accomplish this. Can anybody help me figure out what references I need to add to my Project and what namespaces and APIs I need to use? Thanks.
