R2022a » Steve on Picture Processing with MATLAB


It is March, and you understand what which means — that is proper, the “a” launch is right here!

On most work days, I exploit a number of completely different MATLAB variations, principally growth builds, on 2-3 completely different computer systems. However each March and September, I sit up for visiting mathworks.com/obtain to seize and set up the most recent actual factor.
Picture Processing Toolbox (launch notes) has a number of new deep studying examples, together with this one about anomaly detection instance utilizing pretrained ResNet-18.
Pc Imaginative and prescient Toolbox (launch notes) added rather a lot on this launch. For instance, try the bottom fact labeling enhancements, or the YOLO v4 object detector.

MATLAB releases are all the time onerous to summarize as a result of the scope is so huge. The MATLAB launch notes record roughly 130 completely different enhancements and teams of enhancements, together with 22 speedups. (The attempt block executes quicker, 6x for the documented instance, when the block doesn’t error.)

I wish to poke round on the seemingly small adjustments, like those the place widespread operations that previously required a number of steps have been made simpler and extra environment friendly (allfinite, writelines).

I’m often particularly to see what’s taking place within the MATLAB Math space. As common, there is a lengthy record, however I would like to provide a shout out to one thing that MATLAB creator Cleve Moler labored on and blogged about: new management over tiebreak habits within the spherical operate. I supplied one of many use instances: the algorithm inside poly2mask makes use of a sort of rounding that all the time breaks ties in the direction of +Inf.
Talking of different MATLAB Central blogs, Ned Gulley simply posted a few new device, accessible on the File Alternate, that makes it simple to take a MATLAB dwell script and publish it to WordPress as a weblog publish. That is the device that I frequently use.
