METHODS AND SYSTEMS FOR REMOVAL OF ROLLING SHUTTER EFFECTS

摘要

Methods and systems for rolling shutter removal are described. A computing device may be configured to determine, in a frame of a video, distinguishable features. The frame may include sets of pixels captured asynchronously. The computing device may be configured to determine for a pixel representing a feature in the frame, a corresponding pixel representing the feature in a consecutive frame; and determine, for a set of pixels including the pixel in the frame, a projective transform that may represent motion of the camera. The computing device may be configured to determine, for the set of pixels in the frame, a mixture transform based on a combination of the projective transform and respective projective transforms determined for other sets of pixels. Accordingly, the computing device may be configured to estimate a motion path of the camera to account for distortion associated with the asynchronous capturing of the sets of pixels.

1. A method comprising:
determining, by a device comprising a processor, for a set of pixels, a mixture transform based on a combination of a projective transform and respective projective transforms determined for other sets of pixels including features in a frame of a video captured by a camera; and estimating a motion path of the camera based on the mixture transform and respective mixture transforms to account for distortion associated with sequential capturing of the sets of pixels in the frame.
