I want to spatially rectify an image using a set of control points using IMAQ functions.

I want to spatially rectify one image to another using a set of mutual control points.  I have some Matlab code that will accomplish this but I want to use the Labview/IMAQ fucntions to accomplish it.  I already have a VI that will generate the control points

Has any one run into sample code or any documentation that describs how this can be done?

Hi irfocus,

                See these links:

               Try to provide some more information,post the VI you already have etc:-

Thanks for the info.  I haven't read through it all yet but will do so shortly.  I looked through this stuff previously and only found the ability to rectify or translate an image to a defined mutual pattern.  I can't do that because of the difference in camera technologies  (visual versus thermal IR) I am using whereby a pattern in one image may not exist in its partner image.  So I am trying to rectify to a user defined set of control points. although the math must be precisely the same in the translation, the user input is different. With the documentation you sent me I am hoping that one of these functions allows the input of a set of control points in place of a define pattern.

Any additional thoughts would be appreciated.
