my question is similar to this one: OpenCV: Detect blinking lights in a video feed
I have a LED light, and my camera runs at 30fps. At each frame, I ant to know whether the light is on or not. Similar to the previous question I also want to get the location of that point.
I now wonder how to use openCV for this instance (I am new). It would be easy if the light would just be one pixel, but given considerable background noise and the size of the LED, how can I detect the greatest light source in the image. I have to assume that I cannot set the exposure freely (on an iPhone).
I am new to image processing so how would I got about it?
