一种模糊森林学习方法及其行人检测应用
A Fuzzy Forest Learning Method and Its Application of Pedestrian Detection
摘要
Abstract
To solve the over-fitting problem of Random Forest(RF) learning method for training data,a Fuzzy Forest(FF) learning method is proposed by improving the decision function of every decision node.Firstly,it builds decision function of every decision node on decision tree by using Gauss membership functions to convert the clear decision paths to fuzzy ones.Then,it produces fuzzy path with the product of the fuzzy decision values of all decision nodes which the sample goes through from root node to leaf node.Finally,it computes the prediction result according to each fuzzy path and prediction parameter of corresponding leaf node.The new FF learning method is applied in the field of pedestrian detection for learning and classifying both Haar and Histogram of Oriented Gradient(HOG) features.Experimental results show that FF is better than classical classifiers such as Adaboost,Support Vector Machine(SVM) and RF for improving the recognition rate of pedestrian detection.关键词
