Spatial transformations: Where is the input image? 23

We've talked about using Image Processing Toolbox functions to define an affine transformation and apply it to points. Let's begin to explore transforming images. ... 続きを読む >>

Resetting my expectations: What do users know about new product features? 5

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... 続きを読む >>

Spatial transformations: maketform, tformfwd, and tforminv 115

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

Spatial transformations: Affine 23

To explore spatial transformations of images, we need a simple, nontrivial, and useful transformation. The affine transformation fits the bill. Here's the basic affine... 続きを読む >>
