[Insight-developers] How to Validate the Registration Algorithms

[Vaijanath Narasinga Rao]

Hi to all,
Can someone tell me how do we validate the Registration algorithm. 
Actually i have written an registration algorithm and since i am not 
from Medical background do not really understand the validity of an 
algorithm. The algorithm is quite simple, it finds the region and then 
encloses it in an nearest rectangle. From here it gets the center of the 
rectangle. this is done for both the images. From center coordinates one 
can easily get the translation that needs to be applied. One you get the 
desired translation, use the Co-relation index to find maximum 
co-relation at an angle. Thus we get rotation.

The Application that I am making is an registration algorithm of 
multi-modals.
Your answers will help me in understanding things better,

Regards
Vaijanath
