The MathWorks released a new product line update last week. The new release is called R2006a, thus marking the end for releases named R12, R13, R14, etc. Some of you may have noticed that... read more >>

MATLAB user Paul contacted me recently to ask how to convert 150dpi JPEGs to 300dpi TIFFs. After I asked for more information, he explained that he was working with a publisher who expected all... read more >>

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. ... read more >>

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 >>

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... read more >>
