Have you heard of animated PNG (APNG) files? Are you interested in creating them from MATLAB? They are supposed to be an improvement over GIF for making animations that are viewable in a web browser. (If you have an opinion about this, one way or the other, please share your... read more >>

Today's blog post was inspired by an example written by my friend and Image Processing Toolbox developer, Alex Taylor. A few years back, Alex tinkered with using toolbox algorithms to achieve a pseudo-artistic "posterization" effect, like this: ... read more >>

Today I want to finish up my long-running discussion of Feret diameters. (Previous posts: 29-Sep-2017, 24-Oct-2017, 20-Feb-2018, and 16-Mar-2018.) ... read more >>

What is the shape of a pixel? At various times, I have a pixel as a square (often), a point (sometimes), or a rectangle (occasionally). I recall back in grad school doing some homework where we were treating pixels as hexagons.... read more >>

Last time (if you can remember that long ago), I talked about how to find the maximum Feret diameter of a shape. The Feret diameter, sometimes called the caliper diameter, is illustrated by the diagram below. In a virtual sense, place the object to be measured inside the jaws of a caliper, with the caliper oriented at a specified angle. Close the jaws tightly on the object while maintaining that angle. The distance between the jaws is the Feret diameter at that angle.... read more >>

Last time, I wrote about finding the maximum Feret diameter for an object in a binary image, ending up with this figure:... read more >>

This is the first of a few blog posts about object measurements based on a concept called the Feret diameter, sometimes called the caliper diameter. The diagram below illustrates the concept. Place the object to be measured inside the jaws of a caliper, with the caliper oriented at a specified... read more >>
