Hi gang,
I recently got interested in morphing images to create fade transitions in
movies to improve viewability. I know IDL has morph operators but I found no
practical example on how to make them work for my purposes. Has anyone done
something similar before? Can someone point me in the right direction for
success? As usual any help is appreciated.
Cheers,
Haje
PS: This is not a request to write a software package for me; just a bump in
the right direction would be nice. :)

Hi Haje,
a while ago I did the same, artificially creating transitions between
the individual images used for the creation of a movie. I kept it
simple and just
a) converted the individual images from RGB in HSV,
b) linearly interpolated the Hue, Saturation and Value from the start
to the end image, and
c) converted the interpolated images back into RGB.
The result wasn't too bad.
Regards,
Peter

Guys,
thanks for your suggestions. The d_morph demo is exactly what I need. And
there it was right in front of my nose....

Have you looked at the morphing demo provided with IDL? It's at
examples/demo/demosrc/d_morph.pro

Steve.
