Dear Morphometricians,

I am quite new to the area and I apologize in advance for the trivial
nature of this request. I am working in a project where we aim at
assessing the distortion of fingerprints on various substrates. Our
sample is made of a base (undistorted) fingerprint image and various
distorted marks obtained with that finger. We thought of using TPS to
explore the non-affine distortion components.

We are using points, we called minutiae, as landmarks between the base
and a distorted image to compute the TPS parameters.

It has been quite easy for me to find the adequate function in Matlab
to compute the TPS parameters.

However, I would like now to apply a set a TPS parameters on given
base image to compute its "distorted image". I am currently struggling
with the Matlab code (speed issues) and I was wondering if any of you
would have a potential M-file he/she could share with me.

I thank you in advance for your kind assistance,

Kind regards,

Christophe Champod
