2013-08-14 08:19:44 -0600	commented answer	estimateRigidTransform returns non sensical values I just downloaded the source code `lkpyramid.cpp` and set RANSAC's local parameters as arguments so I can modify whatever I want, haha!

2013-08-14 04:25:07 -0600	answered a question	estimateRigidTransform returns non sensical values Your code looks right. However, to estimate an affine transformation you need at least 3 points, but if these points are all aligned, there is an infinity of solutions, which seems to lead the estimation to result in a degenerate solution. Although that might no longer be true as you set `fullAffine` to `false`, perhaps the function is implemented in such a way that it still needs points that are not aligned. But that is a supposition. What is the result if you add another point? For example: `obj1.push_back(Point2f(0, 0)); scene1.push_back(Point2f(10, 10));`
