I am using openCV to find a particular object, and am trying to find a way to make it locate the object consistently. The object's location will be determined by taking 30 frames and trying to find the best guess based on where it is found in each of the 30 frames. Both the camera and object are (mostly) stationary (the object can move slightly, but optimally it will be stationary during the 30 frames).
This image demonstrates what I'm looking for. I know that the green box may not truly be what would be calculated, I just threw it in there to demonstrate. The red boxes are the guesses on each frame, and the green one is what I'm trying to calculate. Are there any known formulas/algorithms for this, or any references on where to start?
I initially tried to just calculate the mode along the X-axis (ignoring width) (with each estimate rounded so that there would be some similarity), and picking a random rectangle whose x value was in that range for X but that was not giving me a very good estimate.
