Generic image coordinate transformation using a matrix

[Maik Riechert]

Hi,

When I want to undistort photographs I use the lensfunpy library 
(https://pypi.python.org/pypi/lensfunpy) which provides me with a 
coordinates array of shape (h,w,2), that is for each input pixel it 
provides the undistorted pixel location. When using OpenCV I can do 
undistortedImage = cv2.remap(image, undistCoords, None, 
cv2.INTER_LANCZOS4). I saw that there is the skimage.transform.warp 
function but I'm not sure how or if I can use that in my case. I would be 
glad for some directions.

Thanks
Maik
