Where can I find haar cascades xml files?

Question

I'm looking for a website to download haar cascades xml files from. It can be for any objects as long as its a properly working cascade.

You don't need any website: https://stackoverflow.com/questions/11537585/where-can-i-find-haar-cascades-xml-files/67897482#67897482 — Jeru Luke, Jun 29 '22 at 11:52

Go to the opencv folder and check the data folder. You'll find haar-cascades for eyes, face, ears, upper body...:) And they do work properly.

Here's one site http://alereimondo.no-ip.org/OpenCV/34/ Don't know if they work though.

thanks but this damn fortiguard blocks me for accessing that website, any other sites you know of? – user1401950 Jul 18 '12 at 09:06

Thanks, I'm looking for other objects as well such dogs, cats,etc. Basically anything found in pictures – user1401950 Jul 18 '12 at 09:35

So, you need the whole world? :P For dogs etc etc you'll have to create your own xml files i guess. People usually need/want face/ears/nose/lips etc. – praxmon Jul 18 '12 at 09:37

The link doesn't work anymore. Moreover, answer by [electrodrel](http://stackoverflow.com/users/558222/electrodrel) refers to the [OpenCV GitHub repository](https://github.com/Itseez/opencv/tree/master/data/haarcascades), that is a more consistent reference. – Vito Gentile Jul 09 '14 at 08:08

As the link in the previous answer seems to be dead, you can also try to download them from the OpenCV GitHub repository here

If you're using opencv from python, you can use this code snippet to use the built-in haar cascades:

import os
import cv2

cv2_base_dir = os.path.dirname(os.path.abspath(cv2.__file__))
haar_model = os.path.join(cv2_base_dir, 'data/haarcascade_frontalface_default.xml')

There is no data folder in the site-packages any more – Mohsen Sichani Dec 19 '19 at 08:55

@MohsenSichani i used the python code to find the cv2 route and i did indeed find them on the data folder – Mr-Programs May 27 '20 at 15:07

ended up using cv2.CascadeClassifier(cv2.data.haarcascades + 'haarcascade_frontalface_default.xml') – Mr-Programs May 27 '20 at 15:35

Wherever you have cloned the opencv-contrib (if you have made it from source) follow this path afterward and in OpenCV3.1.0 I have these for Python in Ubuntu16 :

mona@mona:~/computer_vision/face_detection/opencv_contrib/modules/face/data/cascades$ ls
haarcascade_mcs_eyepair_big.xml    haarcascade_mcs_nose.xml
haarcascade_mcs_eyepair_small.xml  haarcascade_mcs_rightear.xml
haarcascade_mcs_leftear.xml        haarcascade_mcs_righteye_alt.xml
haarcascade_mcs_lefteye_alt.xml    haarcascade_mcs_righteye.xml
haarcascade_mcs_lefteye.xml        haarcascade_mcs_upperbody.xml
haarcascade_mcs_mouth.xml

In the official repo of openCV in the data folder: https://github.com/opencv/opencv/tree/master/data

Remember: Not everyone uses latest version of openCV therefore you can choose the version of the library through tags in the git repo.

These cascades seem to be somewhat timeless: e.g. this one https://raw.githubusercontent.com/opencv/opencv/master/data/haarcascades/haarcascade_frontalface_default.xml is 5 years old as of now. – Tomasz Gandor Mar 04 '19 at 20:46
Thankyou so much, got the all models. – Aravind R May 22 '22 at 05:16

The xml files can be accessed directly from cv2 like so

cv2.data.haarcascades

heres a more detialed example

face_cascade_name = cv2.data.haarcascades + 'haarcascade_frontalface_alt.xml'
face_cascade = cv2.CascadeClassifier()
if not face_cascade.load(cv2.samples.findFile(face_cascade_name)):
    print("Error loading xml file")
    exit(0)

You don't need to go to other websites to find the cascade classifier files. you just need to go to the opencv releases site. There download the appropriate release. then open the downloaded file. In there direct as followed : sources > data > haarcascades ; In that file you should find the all default haarcascade files.

This is how I do it with git v2.25.0, also tested with v2.26.2. This trick doesn't work with v2.30.1

TLDR

git clone --no-checkout --filter=tree:0 https://github.com/opencv/opencv
cd opencv

# requires git 2.25.x to 2.26.2
git sparse-checkout set data/haarcascades

You can use Docker to avoid installing a specific version of git

git clone --no-checkout --filter=tree:0 https://github.com/opencv/opencv
cd opencv

# requires git 2.25.x to 2.26.2
docker run --rm -it -v $PWD/:/code/ --workdir=/code/ alpine/git:v2.26.2 sparse-checkout set data/haarcascades
