I learned something interesting this week in conversations with MATLAB users. By e-mail and phone I talked with two people who have been reading posts in this blog. Both have the Image Processing... read more >>

Several Image Processing Toolbox functions related to spatial transformations use "tform" structures. A tform structure has data and function handles needed for applying a... read more >>
