Steve on Image Processing with MATLAB

Image processing concepts, algorithms, and MATLAB

All about pixel colors: Summary

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 grayscale and binary image conventions in the Image Processing Toolbox.

For easy reference, here is the entire series:

  1. Introduction
  2. Truecolor and indexed images
  3. Scaled indexed images
  4. Window-level and CLim
  5. Reference information
  6. Grayscale and binary images

[Updated 10-April-2006 to add link to the reference information post.]
