Multi Scale Motion Saliency for Keyframe Extraction from Motion Capture Sequences

We propose an automatic approach to extract keyframes from a motion capture sequence. We treat the input sequence as motion curves, and obtain the most salient parts of these curves using a new proposed metric, called 'motion saliency'. We select the curves to be analyzed by a dimension reduction technique, Principal Component Analysis. We then apply frame reduction techniques to extract the most important frames as keyframes of the motion. With this approach, around %8 of the frames are selected to be keyframes for motion capture sequences.
