| Abstract: | This paper proposed an automatic image mosaic algorithm based on sphere model. First, the algorithm uses SIFT method to get the special point and its feature. Then, the algorithm matches the features with the criterion of nearest neighbor based on confidence. At last the images are mosaic together by projected onto a virtual sphere. After experiments on different images, the results prove that the algorithm greatly enhances the level of automation and accuracy. |
