Figure 3-9.  Using Multiple Regions to Learn Color Distribution
Choosing a Color Representation Sensitivity
When you learn a color, you need to specify the sensitivity required to 
specify the color information. An image containing a few, well-separated 
colors in the color space requires a lower sensitivity to describe the color 
than an image that contains colors that are close to one another in the color 
space. Use the sensitivity parameter of 
imaqLearnColor()
 to specify the 
granularity you want to use to represent the colors. Refer to the 
 section of Chapter 5,
, for 
more information about color sensitivity.
