Is there any function for QR decomposition for opencv?

Basically QR codes are a representation in binary images that should be read as bits. There is no included decomposition algorithm in OpenCV included, but if you know how the bits relate to the algorithm, I guess implementing in C++ wouldn't be that hard.

This link is an example of such a code, you can integrate this with your OpenCV project easily.

:D a different interpretetation of his question. I thought he would like to make a QR factorization of a matrix.

Maybe if the question would be more clear :)

Hmm what, first you describe QR codes, then you link to Eigen's QR decomposition? Very confusing what you're doing here. Actually the question is quite clear - QR decomposition relates to the matrix decomposition, and not to QR codes.
