Paper Abstract

In the process of remote-sensed image fusion with wavelet packet transform, wavelet basis with different properties can exhibit different fusion performance. It is significant to find the best wavelet packet basis and apply it in the process. However, for image fusion, best basis searching algorithm must works within two wavelet packet trees, in the case that the present algorithm only works within one tree. The paper firstly proposes a new searching algorithm working in two trees, then realizes a new image fusion method using wavelet packet transform with the best basis that is developed from the new algorithm. Experiment testifies: under the fusion rule based on texture, the method develops more advantage of wavelet packet transform, and gains a better fusion performance compared with other image fusion method using wavelet packet transform (including wavelet transform).
