As Loren posted yesterday in her Art of MATLAB blog, the R2007a release is available. Readers of this blog might be interested in the minor upgrades the Image Processing Toolbox, the Image... 更多内容 >>

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 ... 更多内容 >>

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 ... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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,... 更多内容 >>

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... 更多内容 >>
