Abstract:
1. A method of stabilizing a sequence of images captured from respective sub-areas of a capture area of an image capture element, the method comprising: receiving data relating to a path of the image capture element during capture of a sequence of images; for a desired size of image, defining, in association with the received data, at least two boundary conditions defining a stabilization band for the sequence; using captured image data disposed within the stabilization band, deriving a stabilization path within the band for the sub-area; defining an associated trellis of length T within the stabilization band: incrementally shifting the position of the trellis with respect to time along the stabilization band; and for each position of the trellis within the stabilization band, deriving a portion of a stabilization path from data disposed within the stabilization band at the position of the trellis within the band.
