Thank you Open CV user forum
Hello,
Specials thanks to @berak and @StevenPuttemans and to all other who helped me getting into the "computer vision" stuff.
You made this possible https://www.youtube.com/watch?v=fImzp...
Is it possible to donate to opencv and if - how?
You are welcome! As @eshirima already said, you can officially donate through Paypal, or support the framework in a more formal manner (hardware, hosting, ...) if it is the latter you want, you will have to try and get hold of Gary Bradski or any of the other top guys at OpenCV. If it is just a small contribution, PayPal is the way to go.
Oh and believe me, the best way of getting something back to the community, is by becoming active in this Q&A and contribute to the framework in the long run, even how small your contributions are.
