Abstract: In view of the HOG with large amount of calculation and the high detection accuracy,through the structural adjustment of the HOG features,the paper put forward that using Fisher feature selection criterion picks out the feature blocks full of ability to distinguish characteristics of pedestrian,and finally produces MultiHOG characteristics.Combined with the Lib-SVM classifier, the algorithm in the paper detects pedestrians with slided windows,and has a higher accuracy and real-time performance than HOG.

Key words: HOG features ,Fisher feature selection,MultiHOG characteristic,SVM classification
