Abstract： |
High efficient digit image large size amplification method based on subspace dissolution characterizes in converting two-dimension image interpolation into several singular vectors one-dimension interpolation containing singular value dissolution, singular value vector one-dimension interpolation and singular value restructure successively and greatly reducing the interpolation complexity by split, the ratio is reduced along with the increase of amplification of the operation time of this invented method and that of the image two-dimension three-interpolation method in a same image dimension and split dimension, such as a split dimesnion is 16*8, amplified dimension is 120 inch, if image three times interpolation is 1, image linear interpolation time is 0.42, image latest interpolation time is 0.295. |
