| Abstract: | A quaternion-based color image matching algorithm has been proposed.Color image is described by quaternion matrices model in this algorithm,and the singular value of the quaternion matrices is extracted as matching feature.De-noise processing to the singular value enhances noise immunity.Hierarchical search strategy is used to reduce computation and improve the matching speed.Experimental results demonstrate the effectiveness of this method. |
