I was wondering if it possible using haar cascade or some other form of classifier, to detect for instance a skull, when it is partly cluttered with something else, such that when the skull has been detected i would be able to remove only the skull part from the image, and leave out the cluttered part.
An example could like this
So the shape of the skull is clear, but what i am interested in here is the item stuck into the skull.. Would it be possible vision wise to separate the thing that it stuck in the skull from the skull, or partly do it?
