Hey I never used OpenCV before. Actually I want to realize a project where I need to count objects in real time from a camera, which can be differenced by theire colors such as red, blue or yellow. For example, I would drop continuously a lot of balls from above the filmed area. At the end I want the total number of red, blue and yellow balls.

Since I dont have any experience in using OpenCV I wanted to know, if such a object detection is possible in real time or close to it.

  • typically isn't trivial and depends a lot on the kind of objects you want to detect and probably track or re-recognize. Commented Jan 26, 2017 at 17:15

Well, it is. But note that you may be limited by your hardware. You should search for sample code that perform object tracking by color in opencv to benchmark your machine. That is, if your problem is performance.
