From the archives: All about pixel colors 7

Posted by Steve Eddins,

When I started this blog in early 2006, one of my first series of articles was called "All About Pixel Colors." These articles discussed how MATLAB associates matrix values with specific screen pixel colors. The series talked about the two fundamental image display models (indexed and truecolor); the scaled... read more >>

All about pixel colors: Summary 29

Posted by Steve Eddins,

This week I wrote the last in a series of postings that discussed how MATLAB associates matrix values with specific screen pixel colors. The series talked about the two fundamental image display models (indexed and truecolor); the scaled indexed image variation; using indexed scaling to program brightness/contrast controls; and the... read more >>

All about pixel colors: Reference information 7

Posted by Steve Eddins,

In this posting I want to summarize all of the factors that control image pixel colors in MATLAB. This information is in the MATLAB documentation, but it is scattered around in several locations. If this is way too much detail... 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 >>
