| Abstract: | Remote sensing image resample is an important process in image fusion, this paper uses quatemion to represent the whole multi-spectral remote sensing images, and quaternion interpolation algorithm is used for resampling of images, and then effect and difference between the quaternion interpolation method and the existed interpolation method are analysis and compared through the image fusion processing of remote sensing image which resampled. The experimental results indicate that the quaternion interpolation algorithm is feasible and superior, and it provides a new technical way for remote sensing image resample. |
| Keywords: | quaternion remote sensing image resample spherical linear interpolation spherical quadrangle interpolation |
