My Opencv LBP cascade for people detection for download

My Opencv LBP 13 stage cascade for people detection. It is only 13 stages learned on 300 of positive people images. It is not trained enough. Training time is only under 1 hour. I have also a more trained version also on 300 people. They are just under testing. This is just what i want to release to public. Enjoy The cascade. It is not that bad. You need to only set the higher minNeighbors parameter. As I sayd it is not trained a lot.

Opencv cascade for people detection conditions of use

Also, Do not worry about the condition of use. Use only on your own risk. That's it. The dataset to train this cascade is only mine. I also colect positive and negative data. I just want to say, that there is also no conditions based on the datasets. There is no others conditions of use.

Cascade classifier LBP great but real value is in Datasets

-data v -vec vec.vec -bg bg.dat -numPos 300 -numNeg 300 -numStages 13  -numThreads 4
-stageType BOOST -featureType LBP -w 32 -h 64 -minHitRate 0.995 -maxFalseAlarmRate 0.42
-maxDepth 1 -maxWeakCount 100

the learning process just increase precalcValBufSize and precalcIdxBufSize. One year ago i have set up Azure server for learning and  64 GB of ram is better than more cores. I would like to write something later about that. It was great to have this kind of computer and 30 000 well prepared positive examples for learning. 

How to use LBP cascade in OPENCV

This code helps you to use the cascade. Complete code you can find in the previous article for Car detection in opencv

 vector human;
 cvtColor(img, img, CV_BGR2GRAY);
 equalizeHist(img, img);
 detectorBody.detectMultiScale(img, human,1.1,50,0|1,Size(5, 10),Size(300,480 ));

 if (human.size() > 0) {
  for (int gg = 0; gg < human.size(); gg++) {
                 rectangle(img, human[gg].tl(), human[gg].br(), Scalar(0, 0, 255), 2, 8, 0);
                }
        }
