Abstract:
To stabilize video (an image sequence), reconstructed block data and decoding information of a video frame are received by unit of macroblock from a decoding circuit. Global affine parameters are determined and provided based on the reconstructed block data and the decoding information, and the global affine parameters represent an affine transform of a frame. Stabilized block data are provided based on the global affine parameters by compensating the reconstructed block data for an affine motion corresponding to the affine transform.
