At least create a (e.g. 5x5) window around this pixel and calculate the centroid of this window. This should give you some subpixel accuracy. Web1 de out. de 2024 · The built-in template matching function of OpenCV is robust but only if you have positional invariance requirement. It fails if the object in the live footage rotates with respect to the master image. Another algorithm explored was feature-matching. This ticked all the boxes. It is positional, rotational, and scale-invariant.
