Thanks a lot, this helps, please, post as answer, probably will be useful for somebody else.

just for debugging purposes of ny algorithm. I can assume I need to rebuild whole opencv to have this method?

Hi,

I cannot find getBackgroundImage() method for BackgroundSubtractorMOG2 in java library. Am I mising something?

May be there is alternative way how to get background in java?

Thanks.

Have a look here, described all possibilities configuring with SBT:

Unfortunatelly haar classifier is far from ideal. Try to combine object tracking algorithms, like camshift with haar recognition, use haar to capture object and then track it with other algorithm.

What do you want to achieve btw?

Hi,

You can try to train Haar classifiers to recognize the suit for cards, here is article with detailed explanations how this can be done: http://coding-robin.de/2013/07/22/train-your-own-opencv-haar-classifier.html

However this is not simple task as you will require a lot of positive/negative samples for this.

To recognize the numbers - I think there should be existing solutions, here is good source on OCR: http://blog.damiles.com/2008/11/basic-ocr-in-opencv/

Also you can use findContours to separate cards from each other.

This is not a simple task, if you are really interested - post here your findings and code and I can help to get you tight direction.
