(a) Optical image
(b) Radar image
(c) Registration checkerboard result
Figure 3: Registration: the optical and the radar images represent the same area with a deformation. A six parameters transform is
computed (translation, rotation, scaling) using the mutual information as a similarity measure.
(a) Panchro image
Figure 4: Pan-sharpening example: high resolution of the panchromatic image is introduced in the multispectral image to obtain a
multispectral high resolution image with a basic method.
