Missing haarcascades xml files

[skvark]

Thanks for the report, I'll add them to the package in next release. I have to go first through the licenses of those files. Most of them seem to be under BSD-like license so shouldn't be a problem to include them.

I had a better look into this. That tutorial is a bit misleading since it's not very clear on where the script has to executed:

"Those XML files are stored in the opencv/data/haarcascades/ folder."

Now, even if I distribute all the XML files with this package the following line won't still work because it tries to read the XML file from the same folder where your script is executed:

face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

If I add those files in the package, you will have to use something like this:

haarcascades_path = os.path.dirname(cv2.__file__) + "/haarcascade_frontalface_default.xml"
face_cascade = cv2.CascadeClassifier(haarcascades_path)

The haarcascades path can be accessed now via cv2.data.haarcascades.

Great, thanks!

Maybe add from cv2 import DATA as a helper for os.path.dirname(cv2.__file__)?

Or maybe even a constant cv2.data.haarcascade if there are not many files.

[skvark]

Yes, I was thinking about something like cv2.data.haarcascades which is the path to the folder which contains the haarcascade files.
