Apply transformation matrix to image

Hey,

I have used the algorithm "Absolute Orientation - Horn's method" by Matt J in order to undistord an image. As a result I got a 3x3 transformation matrix. I would like to apply this transformation matrix to an image now. Does anyone know how to do it? The transformation matrix looks like this:

regParams.M

ans =

    0.9763    0.0024  205.7496
   -0.0024    0.9763  337.0974
         0         0    1.0000
         
         

Thank you so much in advance!

Hi,

As per my understanding, you want to apply the transformation matrix on to an image. This task can be achieved using imfilter() or conv2(). Using these functions, you can slide the transformation matrix (or kernel) across an image.
