A possible case of an initially incorrectly perceived stimulus is mistaken identity. Instances of mistaken identity can happen when the observer looks at somebody from a distance or obscure angle. The "bottom-up" processing gives an unclear image of the person being observed. Hence the "top-down" processing of the observer tries to fill in the gaps and come to a conclusion about the person being observed.
However, it's possible for the observer to come to an incorrect conclusion about the person they're observing. This often occurs because the "top-down" processing of the observer notices the resemblance the stimulus has to someone the observer is familiar with. Hence, they can come to an incorrect conclusion about who they're observing.
However, once the "bottom-up" processing gives a clearer picture of the person they're observing, their premature conclusion is proven wrong. Thus, the observer mistook the identity of the person they were observing due to an incomplete image given by their "bottom-up" processing, and their "top-down" processing driving them to an incorrect conclusion.
