correction of parallax (or positional discrepancy)

naoki irie
Hello,
I'm having problem with converting images to stack with no positional
discrepancy.
Is there any plugin that I can correct parallax (or positional
discrepancy between images)
automatically?

When using "Stack Focuser", images withougt positional difference returns
the best result. But the only way I know to correct positional discrepancy
between images is to use the Photoshop and adjust them manually.
-Make images into semitransparent layer and adjust the positional
discrepancy.

If anyone who knows the plugin that solve this problem automatically,
please help me.
Thank you

Naoki Irie

I use to apply a linear filter made of a displacement matrix :


For instance :


0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 00 0 0 0 0

Sorry for my preceding message.

To move an image, I use a filter made with a displacement matrix, such as :


0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 1
0 0 0 0 0

Which has for effect to move the image rightwards of 2 pixels and downwards of 1 pixel. To get the ideal displacement, I use photoshop too.

Does it help ?

Dear Dr. Sheffield , Dr.Tourneur


Thank you very much for helping me with the problem.

TurboReg   http://bigwww.epfl.ch/thevenaz/turboreg/

and

StackReg   http://bigwww.epfl.ch/thevenaz/stackreg/

worked just perfect to correct the positional discrepancies.
