Extrapolation of Wavelet Features for the Indexing of Satellite Images with Different Resolutions
2006
2006 IEEE International Symposium on Geoscience and Remote Sensing
Preserved Fulltext
By explicitly taking into account the acquisition process of satellite images, we compute how wavelet features behave when the resolution changes. ...
In this paper, we propose a new scheme to extrapolate wavelet features with respect to the resolution. ...

However, most of our observed structures could not be explained with simple resonances with external satellites and some other mechanism has to be involved. ...
