I trying to train haar cascade classificator for card suite detection (which no rotation and has no distortion on image)

For example I have file Clubs.png which contents clubs image on white background 20x20 pixels

This tutorial is so tangled http://note.sonots.com/SciSoftware/haartraining.html

My image varies only in sizes, no distortion or angling.

Which commands I must enter in aim to get Clubs.xml file?

As @Neon22 mentioned, great tutorial. From my experience, it's quite a lengthy process(collecting positive and negative samples, training, generating haar cascade), but then again maybe I was doing it wrong.

For detecting cards, it might be useful to have a look at OpenCV SURF as well.

Check out toxi's video.

Funny you mention cards, Eugene Zatepyakin did an actionscript port called ASSURF:
