14 Mar 2009 B-spline Grid, Image and Point based Registration B-spline registration of two 2D / 3D images or corrsp. points, affine and with smooth b-spline grid. Author: Dirk-Jan Kroon

Thanks a lot DIrk-Jan Kroon.

Your script works really great on our machines. One more thing, my research group has access to a cluster and we'd love to run your alignment program on it. I was wondering how difficult would it be to change the .c files so that they can also be compiled on Linux. Any thoughts on this issue?

Dirk-Jan Kroon ,

Thanks a lot for sharing this great piece of work with us. This is a very nice contribution to the Mathworks file exchange repository.

I have one question about your code though. I am looking at your submission on Mar 4. When I run one of your examples, e.g. example_2d_nonrigid_1.m, the results figure shows four images, and I am not sure I understand what is being displayed.

Shouldn't 'transformed image 1' (Icor in your code) be the result of registering Image 1 (I1) onto image 2 (I2)? If so, 'transformed image 1' should look similar to 'image 2', right? However, in your figure 'transformed image 1' resembles more image 1 than image 2. Am I missing something? Is the registration really working in this example?

Thanks a lot!
Best,
AmR

Hi Berkin,

Thanks for sharing this. Could you please also upload the images yos9.tif and yos10.tif referenced in the demo.m file?

Thanks!
Best,AV
