Description

Came around this one while trying to understand why some estimated trasnforms were completely wrong:
if RANSAC used in cvEstimateRigidTransform doesn't find correct solution it returns 0 but cv::estimateRigidTransform only returns the supposedly estimated transform matrix! So if no solution is found an uninitialized matrix is provided and no warning message provided...

estimateRigidTransform should return 0 or 1 and pass transformation matrix as reference/

looks like the problem in C++ wrapper. Need to check the return value and return empty matrix if cvEstimateRigidTransform() returned 0.
