Patent Images
1. A machine-implemented method, comprising:
- determining a filtering apportionment distributing a first filtering task to a graphical processing unit and a second filtering task to a central processing unit based on a prior filter performance;
applying a rolling shutter effect correction filter to an initial version of a video data set;
warping an image of the initial version by applying a motion vector set using the graphical processing unit;
adjusting a warping constant on the motion vector set based on a previous iteration; and
applying a video stabilization filter to the initial version to produce a final version of the video data set.

Abstract
In one embodiment, a video processing system 300 may filter a video data set to correct skew and wobble using a central processing unit 220 and a graphical processing unit 230. The video processing system 300 may apply a rolling shutter effect correction filter to an initial version of a video data set. The video processing system 300 may simultaneously apply a video stabilization filter to the initial version to produce a final version video data set.
