7.4.2 Color Blob Tool
One way to conduct a color inspection is to group adjacent pixels within the same color range together to form a Blob,
or Binary Large OBject .
The Color Blob Tool is used to separate same color Blobs from the larger scene and to analyze parts with color variations
that cannot accurately be detected by gray scale sensors.
The Color Blob tool can be used to detect parts with either different or similar colors. In addition, the Color Blob tool
can give area, shape and spatial content.
