I'm processing a video of a person but their head is really shaky. What is the best way to "stabilize" the head? Is there any way a can select an object in the face (the nose or an eyes) and try to find a translation value for the next frame in order for that object to be in the same position in the whole video? I have searched for solutions but they warp the imagem I can't have any warping.

Use findHomography to get the right transformation matrix.

...with SIFT or SURF (eventually ORB) detector to get the keypoints, and a FLANN or BF matcher to find the matching pairs.

Try this tutorial to begin with: https://docs.opencv.org/2.4/doc/tutor...
