Embodiment Construction
[0027] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0028] 1. Pedestrian detection and face detection
[0029] Pedestrian detection and face detection are implemented using Adaboost algorithm.
[0030] 1.1 Adaboost algorithm
[0031] Given a sample image set (x 1 ,y 1 ),..., (x n ,y n ), where y i ={0, 1} represent negative samples and positive samples, respectively. Initialize weights: w 1 , i = 1 2 m , 1 2 l respectively corresponding to y i = 0, the weight of 1 sample (because m × 1 2 m + l × 1 2 l ...
