I want to use LBP and Random forest,but I don't know how to get LBP feature for Random forest training? can anyone help me

I want to use LBP and Random forest,but Forest, but I don't know how to get the LBP feature features for Random forest training? can training?

Can anyone help me out?

I want to use LBP and Random Forest, but I don't know how to get the LBP features for Random forest training?

Can anyone help me out?

Mat train_features; // 1 row for each lbp feature, float !
Mat train_labels    // 1 row (containing 1 float element with the id) for each feature

CvRTrees tree;      
CvRTParams cvrtp; // set params, play with those!! (the numbers were for my problem)
cvrtp.max_depth = 25; 
cvrtp.min_sample_count = 6;
cvrtp.max_categories = 2;
cvrtp.term_crit.max_iter = 100;

tree.train ( train_features , CV_ROW_SAMPLE , train_labels,cv::Mat(),cv::Mat(),cv::Mat(),cv::Mat(),cvrtp );

// later:
float id = tree.predict(sample); // where sample is a lbp feature , again

sorry..... you give me the link, I want to use LBP and have see, the train function base on Random Forest, but I don't know how to get Forest？what is the LBP features for Random forest training?

Can anyone help me out?

EDIT 1 :

Mat train_features; // 1 row for each lbp feature, float !
Mat train_labels train Algorithm？
I'm new hand in    // 1 row (containing 1 float element with the id) for each feature

CvRTrees tree;      
CvRTParams cvrtp; // set params, play with those!! (the numbers were for my problem)
cvrtp.max_depth = 25; 
cvrtp.min_sample_count = 6;
cvrtp.max_categories = 2;
cvrtp.term_crit.max_iter = 100;

tree.train ( train_features , CV_ROW_SAMPLE , train_labels,cv::Mat(),cv::Mat(),cv::Mat(),cv::Mat(),cvrtp );

// later:
float id = tree.predict(sample); // where sample is a lbp feature , again

I want like this,but I don't konw How to create the train_features matrix element. Anyone can help me out here?openCV
