In order to solve the problem of image blur stitching caused by the obvious geometric deformation and the changes of the scale and light among images and reducing the high computation cost,a new accelerating method of image mosaicis is presented.The feature points are extracted based on Harris and the eigenvectors of feature points are created by Multi-resolution Analysis.By using principal component analysis,the dimension of eigenvectors can be greatly reduced and the operational efficiency of image feature matching can be improved with almost no losses of information of the original eigenvectors.Experiments have shown the effectiveness of this stitching method.
