Opencv 3.1 people detection by CascadeClassifier

People detection by Cascade Classifier Opencv

The comparison of Opencv Cascade for people detections. Default opencv cascades are good one. You can simply achive better result but you need to collect the training data. On my blog you can find the datasets for car detection. There is more than 2000 positives car samples available for you and test to learn your own detector.. 

Here in this article, I just want to show my cascade compare to cascade which are default in opencv. 

LBP cascade for people detection

Also I recently publish LBP cascade for people detection. You can download 12 stage LBP cascade LBP cascade for download. There is couple or maybe more than 3 tutorials how to use detect multiscale in opencv. Just download the LBP cascade and enjoy coding in Opencv..

Haar Cascade Classifier for People detection

In this short tutorial, I would like to test some standard haar cascade in opencv 3.1. 

My first note is where you can find this cascades.

When you download opencv for windows this cascades are located in opencv/sources/data/haarcascades

In the picture i use these types of cascades. 

haarcascade_fullbody.xml

haarcascade_upperbody.xml

haarcascade_lowerbody.xml

Visually, i can rate the cascade as rly great for fullbody an lowerbody. The upperbody cascade has trouble with my source video. Which is not its fault.

Own haar like cascade

Also, I am testing some of mine own haar cascade, which are learned by different methods like gentle boost, adaboost, etc.

Red and blue are the cascades for people detection. White is haar cascade for head detection. Check the video for results.

Video of mine haar cascade.

UPDATE

Code is HERE and cascade is LBP cascade for download
