Abstract
Described herein are apparatus, systems and methods for synchronizing a reference video with an input video. A method comprises extracting first motion data from the input video having a first set of frames, extracting second motion data from the reference video having a second set of frames, computing motion descriptors for each frame in the first set of frames and the second set of frames based on the first and second motion data, respectively, and non-linearly mapping the first set of frames to the second set of frames based on the motion descriptors, respectively.
