Head and people detection in opencv

LBP cascade free to download to use in opencv to detect people and heads. Code example and cascade description. All you need to write your own people head detector from the youtube video.
Cascade is trained on my own people and head datasets. There are no perfect but in some cases are better then default opencv cascades. They are just different.. For example, you can count that the head detector have much more false detection than the people detector.. The shape and feature space is much more common and close to others shapes than the whole people detector.

Issues with opencv detectMultiScale head and people detector

Please let me know if the cascades worked as expected.. In code example there is ground threshold settings and reccomentation.

Opencv cascade for car detection conditions of use

Also, Do not worry about the condition of use. Use only at your own risk. That's it. The dataset to train this cascade is only mine. I also collect positive and negative data. I just want to say, that there is also no conditions based on the datasets. There is no other conditions of use. Maybe check the Opencv train cascade utility. Thanks. Yes, share and cite. Just small minimal conditions like send me a million dollars. It's up to you.

Head and people detection tutorial code

You can simply prepare the project inside the Visual Studio 2015 by Nuget Packages. This approach is easy for beginners and better than standard installation with all the environmental variables problems. Just follow the installation steps here

This code is based on my previous tutorial Fast people detection.
Inside the video capture loop just modify the part like this. Include cascade inside your project and play with different settings.. This is not an ideal one.

// Name of the downloaded my cascades.. 
 string cascadeHead = "cascadeH5.xml";
 string cascadeName = "cascadG.xml";
// Load the cascade
 CascadeClassifier detectorBody;
 bool loaded1 = detectorBody.load(cascadeName);
 CascadeClassifier detectorHead;
 bool loaded2 = detectorHead.load(cascadeHead);

 detectorBody.detectMultiScale(img, human, 1.0440 | 1Size(3080), Size(80,200));
 detectorHead.detectMultiScale(img, head, 1.140 | 1Size(4040), Size(100100));
 if (human.size() > 0) {
  for (int gg = 0; gg < human.size(); gg++) {
   rectangle(original, human[gg].tl(), human[gg].br(), Scalar(00255), 280);
 if (head.size() > 0) {

      Code is same cascade is different.. There is lots of cascade detect faces. I do not spent time to doing training of that detector..

    Hi. I'm using the head cascade in my project.
    And my question is if the parameters are the same with the face cascade. All this implemented from python. Also, what would be the correct syntax to call the cascade.
    Thanks for your help.

    Do you have implementation in Python? of the same LBP cascade?

    I need some suggestions on training data more precisely. can you guide me to train my own cascade in a efficient way.
    It would be really helpful for me.
