What does Imwarp do in Matlab?
imwarp determines the value of pixels in the output image by mapping locations in the output image to the corresponding locations in the input image (an inverse mapping).
How do you apply a transformation to an image in Matlab?
B = imtransform( A , tform ) transforms image A according to the 2-D spatial transformation defined by tform , and returns the transformed image, B . If A is a color image, then imtransform applies the same 2-D transformation to each color channel.
