Building Computer Vision Projects with OpenCV 4 and C++

Does it work well?

There's a reason we call it the naive approach! It works under ideal conditions and, as we know, nothing is ideal in the real world. It does a reasonably good job of computing the shape of the given object, but it does so under some constraints. One of the main requirements of this approach is that the color and intensity of the object should be sufficiently different from that of the background. Some of the factors that affect this kind of algorithm are image noise, lighting conditions, and autofocus in cameras.

Once a new object enters our scene and stays there, it will be difficult to detect new objects that are in front of it. This is because we are not updating our background model, and the new object is now a part ...
