opencv object detection only scale not rotation

SIFT and SURF is scale and rotation invariant. I want to detect object that is only scale invariant. Are there any function or sample code / function in openCV that can do this. I do not want rotation invariant only scale invariant.

BRIEF is not designed to be rotation invariant.

Citing from original paper:

Orientation Sensitivity: BRIEF is not designed to be rotationally invariant. Nevertheless [...] it tolerates small amounts of rotation.
