MATLAB: Perform coordinate transformations on partitioned images to match feature points of two images

Question

Hi, I need to code image morphing in matlab.As a part of the algorithm I need to perform coordinate transformations on the partitioned images to match the feature points of these two images. The coordinate transformations are affine transformation or bilinear transformation.

Example of two images:

image1: http://www.crocko.com/92A5F93912BD411C81D5DAFD26492575/ally.jpg

image2: http://www.crocko.com/EF180CF97EE3449CA8829AF82BC2AD71/lion.jpg

Output after transformation:

image1 transformed: http://www.crocko. com/407346490C1749BF97F1AC60584C8732/warped_ally.jpg

image2 transformed: http://www.crocko.com/38CF6AE816E44DAF885AD208F5F29D59/warped_lion.jpg

Equations for the coordinates transformation: http://www.crocko.com/B7A01EC313684CEBB00CD416EF9FD0CA/affine_eq.jpg http://www.crocko.com/1859259A957A4C71A0C58CD0C0079164/bilinear_eq.jpg

The question is how to code the transform in matlab? Does anybody can share an idea or similar made code to perform the necessary coordinates transformation on two images in loop and to get the results above?

I can't see your images, just some ad for a web hosting service. Try tinypic.com instead.
