From: Handling missing weak classifiers in boosted cascade: application to multiview and occluded face detection

Figure 13

Performance of classifiers produced with the three cost functions: TP_cost, FP_cost and FP_TP_cost. In (a, b, c), 50% of the weak classifiers are unavailable, while 60% of the weak classifiers are unavailable in (d, e, f). In (a) and (d), posterior probabilities are computed with P boost. In (b) and (e), P knn is used, and P comb is used in (c) and (f). The number of neighbors in P knn and P comb is fixed at 3.
