Tracing George 104

Posted by Steve Eddins,

Last time, in my spatial transformations series, I introduced the head-and-shoulders outline that I like to call George (George P. Burdell). Today I want to diverge briefly from my main topic and show how I recently "recovered" George. ... read more >>

All about pixel colors: Window-level and CLim 10

Posted by Steve Eddins,

In a comp.soft-sys.matlab newsgroup post on January 17, Kevin wanted to know how the brightness/contrast control in imtool worked. Image Processing Toolbox function imtool is an image viewing/navigation GUI. ... read more >>

All about pixel colors: Scaled indexed images 52

Posted by Steve Eddins,

In my last post on pixel colors, I described the truecolor and indexed image display models in MATLAB, and I promised to discuss an important variation on the indexed image model. That variation is the scaled indexed image, and the relevant MATLAB image display function... read more >>

Spatial transformations: Terminology and notation 8

Posted by Steve Eddins,

"Terminology and notation" - is there a more boring way to start a topic? Unfortunately it's necessary, because there is a lot of variation in terms and equations from book to book and paper to paper. Some of the "frequently-asked questions" arise from simple confusion over notations and conventions. Even... read more >>

Spatial transformations 10

Posted by Steve Eddins,

Section 5.11 of Digital Image Processing Using MATLAB covers spatial transformations. I'm interested in expanding this material to a full chapter. I'd like to use this blog to explore these topics and get your feedback about them. ... read more >>
