Abstract(in English)	In this paper, we develop a fast algorithm for random-projection-based global registration. By generating many transformed images from the reference, the nearest neighbour based image registration detects the transformation which establishes the best matching from generated transformations. To reduce computational cost of the nearest nighbour search without significant loss of accuracy, we first use random projection. To reduce computational complexity of random projection, we second use spectrum-spreading technique and circular convolution.
