METHOD, SYSTEM AND APPARATUS FOR STABILISING FRAMES OF A CAPTURED VIDEO SEQUENCE

A method of stabilising a captured video. The method includes receiving a set of reference patch locations in a reference frame and reference patch alignment data for each location and receiving a frame of captured video. A first offset and a first subset of patch locations are selected from the set of reference patch locations. A second offset more than a pre-determined distance from the first offset and a second subset of patch locations from the reference patch locations are selected. The method further includes analysing image data for the frame of captured video at each patch location of the first and second subsets according to the corresponding reference patch alignment data to generate corresponding shift estimates; analysing the shift estimates to generate corresponding alignment transforms and confidence metrics; and selecting one of the alignment transforms according to the confidence metrics for stabilising the video.
