Is there a very basic color/shape detection mechanism through which one could detect a specific color or a shape in a webcam feed? Wanted to use the color/or shape as a symbolic marker for an AR application. Though the ideal case would be a NFT , but i am not much of coder and have no experience in OpenCV( have read a lot about it in previous discussions here).Have worked so far with the SLAR tooolkit only and that offers only the basic b/w marker detection And the more easily useable NFT libraries are , well, not freeware :/
Any guidance to integrate the abovementioned detection routines in a .Net/Flash environment would be of great help.
Color detection is very easy: take your videostream images, convert them to binary images by using the RGB value as a vector (like RGB = [0,255,0] = green), and setting other vectors within a given distance as positive hits. This is one of the easiest forms of computer vision, and a couple of early CV-based PS2 games involved detecting brightly colored props.
This is my favorite paper on shape recognition - if you want to detect simple 2D outlines on flat surfaces, this is a great technique.
I'm neither a .Net or a Flash programmer, so I can't offer any help there.
