fuses much better and results in high match scores—around 800—for both

Choosing a Color Representation Sensitivity
When you learn a color, you need to specify the granularity required to
specify the color information. An image that contains a few well-separated
colors in the color space requires a lower granularity to describe the
color than an image that contains colors that are close to one another
in the color space. Use the
ColorSensitivity parameter of
CWIMAQVision.LearnColor to specify the granularity you want to
use to represent the colors. For more information about color sensitivity,
refer to the
Color Sensitivity section of Chapter 5, Performing Machine
Vision Tasks .
