When I started this series, I naively assumed that Image Processing Toolbox users who were interested in spatial transformations would already know about the function <tt>imtransform<\/tt>. I was wrong about that, as I've already <a href=\"https:\/\/blogs.mathworks.com\/steve\/?p=43\">written<\/a>.<\/p>\n<p>You can use <tt>imtransform<\/tt> and <tt>maketform<\/tt> to apply several types of transformations to images, including affine, projective, and custom. In addition, the image registration function <tt>cp2tform<\/tt> can make more types of transforms, including linear conformal, polynomial, piecewise linear, and local weighted mean. Since it's going to be a few more weeks before I get into the specific details of <tt>imtransform<\/tt> and friends in this blog, I thought I'd provide some pointers to help readers who need the information now.
