Last week The MathWorks released R2008a, the ninth in a series of six-month releases. (If there's an equinox coming up, look for a new MATLAB® release!)
Here are some of the highlights especially... read more >>

Earlier this year I exchanged e-mail with blog reader Craig Doolittle. Craig was writing MATLAB scripts to clean up scanned pages from old manuscripts. One of the samples he sent me was... read more >>

In a blog comment earlier this summer, someone asked how to find "which labeled regions have a bright spot greater than some threshold?" That's a good question. It can be done efficiently... read more >>

One the measurements provided by regionprops is 'Centroid'. Here's an example of labeling binary objects, computing the centroid of each object, and plotting the centroid location on top... read more >>

The functions bwlabel and regionprops are very useful for measuring the properties of shapes in a binary image. There are documentation examples and product demos showing how to do this,... read more >>

Patrick asked for an example on how to compute distances between objects based on resolution information stored in a file. The TIFF format
is one that can store resolution information, and the... read more >>

A post in comp.soft-sys.matlab this week (see the third post in this thread) asked how to display graphically the numerical labels associated with each labeled object. In this blog I'll show a... read more >>

Recently, our application support engineers gave a series of presentations to development groups. These presentations summarized calls received by tech support about different products. I thought... read more >>

Blog reader Jonathan from St. Jude Children's Research Hospital sent me an image derived from an MRI peg phantom:bw =... read more >>
