Generic platform video image stabilization

A method of digital video stabilization, the method comprising performing steps on a computing device of:

• performing local motion vector estimation for a frame of a plurality of frames of a scene of a video segment, wherein the local motion vector estimation comprises for said frame:
• downsampling said frame and a reference frame associated with said frame by one or more times to form a plurality of versions of said frame at a plurality of resolutions, wherein a lowest resolution version of said frame has a plurality of blocks associated as a pyramid structure to a successively larger number of blocks at corresponding locations in each higher resolution version of said frame;
• for the lowest resolution version of said frame, estimating motion vectors of the blocks of said lowest resolution version frame using an initial motion vector estimation processing of the associated lowest resolution version reference frame;
• for each successively higher resolution version of said frame, estimating motion vectors of the blocks of said successively higher resolution version frame using a refinement search starting from the motion vector estimated for the associated block of the preceding lower resolution version frame according to the pyramid structure;
• and
• producing estimated local motion vectors for the blocks of the original resolution version of said frame;
• processing the estimated local motion vectors of said frame for estimation of a global motion transform representing jittery video motion, including selecting a set of motion vectors to use for estimation of the global motion transform out of the produced estimated local motion vectors of said frame, wherein said selecting the set of motion vectors comprises one or more of:
• excluding motion vectors on picture boundaries,
• excluding motion vectors having a high motion compensation residual, and
• excluding motion vectors for blocks with low image content variation;
• and
• performing image warping on said frame based on the global motion transform estimated for said frame to compensate for the jittery video motion.
