Joint video stabilization and rolling shutter correction on a generic platform

摘要

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.

主权项

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.
