it is reasonably quick and provides good approximations to the
optimal solution in the general case. Our motivation for choosing
FLDA is as follows. Since object detection is basically a two class
problem, FLDA might provide quick answer as it comes with a closedform
solution. This procedure directly outputs the optimal weights
and, therefore, the optimal values of and p need to be computed
only once. This makes FLDA much faster when compared to GA or
brute-force methods.
