In this paper, we develop an efficient algorithm for nearest-neighbour-search (NNS)-based global image registration. By generating many transformed images as an image dictionary from a reference image,
NNS-based image registration computes the transformation that establishes
the best match among the generated transformations. To reduce the computational cost of NNS without significant loss of accuracy, we first use random projection. To reduce the computational complexity of random projection, we next use a spectrum-spreading technique and circular convolution. Furthermore, to reduce the space complexity of the search space, we introduce interpolation into the image dictionary using the local linear property of images. |
