Several readers commented on my recent roipoly and poly2mask posts, and I wanted to follow up on a couple of issues they raised. The first issue is a common point of confusion about ... read more >>
Last week I wrote about a possible modification to poly2mask that would estimate how much of each pixel is contained within a polygon. The idea was to use a regular 5-by-5 subgrid and ... read more >>
In December I wrote several blogs about the algorithm underlying the poly2mask function. Basically, the algorithm uses a 5-by-5 subpixel grid and lays out the polygon along the edges of the... read more >>
Item 1: Digital image correlation for strain measurement The iMechanica web site has an item on a MATLAB tool that applies digital image correlation techniques for measuring material... read more >>
I started this blog on image processing and MATLAB about a year ago. Shortly afterward, another blogger discovered it and told the world that a blog solely about MATLAB and image processing was... read more >>
Several people have asked me recently how to plot some kind of shape on top of an image, so I thought I'd show the basic technique here. Essentially, you display the image, then call hold on,... read more >>
A couple of weeks ago I asked if anyone could guess what this "equation" means on my office whiteboard: It's related to the color management approach standardized by the International... read more >>
