The comparison of Opencv Cascade for people detections. Default opencv cascades are good ones. You can simply achieve better results but you need to collect the training data. On my blog, you can find the datasets for car detection. There are more than 2000 positive car samples available for you and test to learn your own detector.
Here in this article, I just want to show my cascade compared to a cascade which is the default in OpenCV.
LBP cascade for people detection
Also, I recently published an LBP cascade for people detection. You can download 12 stage LBP cascade LBP cascade for download. There are a couple or maybe more than 3 tutorials on how to 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.
3.1.
My first note is where you can find these cascades.
When you download OpenCV for windows these 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 really great for fullbody an lower body. The upper body cascade has trouble with my source video. Which is not its fault.
Own haar like a cascade
Also, I am testing some of my own haar cascades, which are learned by different methods like gentle boost, adaboost, etc.
Red and blue are the cascades for people detection. White is a haar cascade for head detection. Check the video for results.
Video of mine haar cascade.
