Motion estimation through input perturbation

An apparatus for graphics processing, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• generate at least one first motion vector in a first subset of a frame, the at least one first motion vector providing a first motion estimation for image data in the first subset of the frame;
• perturb the image data in the first subset of the frame;
• generate at least one second motion vector based on the perturbed image data in the first subset of the frame, the at least one second motion vector providing a second motion estimation for the image data in the first subset of the frame;
• compare the at least one first motion vector and the at least one second motion vector by determining whether a difference between the at least one first motion vector and the at least one second motion vector is less than a threshold;
• determine at least one fourth motion vector for motion estimation of a second subset of the frame when the difference is greater than the threshold, the second subset of the frame being different than the first subset of the frame;
• and
• determine at least one third motion vector for the motion estimation of the image data in the first subset of the frame based on the comparison between the at least one first motion vector and the at least one second motion vector, wherein the at least one third motion vector is set to be the at least one first motion vector when an absolute value of the difference is less than the threshold, wherein the at least one third motion vector is set to have a motion value of zero when the absolute value of the difference is greater than or equal to the threshold, wherein the at least one third motion vector is determined based on the at least one first motion vector, the at least one second motion vector, and the at least one fourth motion vector.
