Abstract

In an aspect, there is provided a method for performing digital image stabilization (DIS) on a sequence of video frames captured by an image capturing device, comprising: obtaining a sequence of motion values sampled from a motion signal while capturing the sequence of video frames such that each video frame is associated with a respective motion value; obtaining a sequence of position values sampled from a position signal while capturing the sequence of video frames such that each video frame is associated with a respective position value; determining, for each respective video frame, a residual motion value to obtain a sequence of residual motion values for the sequence of video frames; and performing DIS on the sequence of video frames, comprising: detecting an image feature in a reference video frame of the sequence of video frames; tracking the image feature in each further video frame of the sequence of video frames; determining frame motion data based on a displacement for the image feature in each further video frame in the sequence of video frames; and generating a stabilized sequence of video frames based on the frame motion data; wherein a size of a tracking window for tracking the image feature in each further video frame is set based on the sequence of residual motion values.
