Matching things up - SIFT Landmark matching via OTB
SIFT and SURF. Transforms can be calculated from 2 sets of landmark points using an appropriate model. I had some trouble bringing it to Qgis, the output is just one band. The sample code needs to be extended to work with multi-band images. The in-memory representation of the match images is in double, this can cause array allocation failures. Otherwise this feature matching provides correlation free image matching for images with different dynamics - such as SAR to Optical.
