A Modified Adaboost Algorithm to Reduce False Positives in Face Detection

Table 1

Comparison of the Viola–Jones and the proposed algorithm; the number of false-positive results is almost four times lower using the proposed algorithm.

	True positive; (detecting faces)	False positive	False negative (missing faces)	Precision, TP/(TP + FP)
Viola–Jones algorithm	220	495	20	30.8%
Proposed algorithm	216	115	24	65.3%
