Banner PresencePLUS P4 COLOR Series - Manual (Page 187)

Min Radius and Min Radius Position
The minimum radius of a blob is the distance from the centroid of the blob to the closest pixel on that blob's perimeter.
The minimum radius position gives the pixel coordinates of that closest perimeter point. If the blob contains unfilled
holes, the minimum radius position may be on the perimeter of a hole. If the camera is configured to convert pixels to
other units, the minimum radius (but not the minimum radius position) will be given in those units.
Max Radius and Max Radius Position
These results are equivalent to those for the minimum radius, but they refer to the pixel on the perimeter of the blob
that is farthest from the centroid .
Color Blob Tool Color Map Visualization
Hue, Saturation, and Intensity is a representation of color space that is closer to human perception of color dynamics.
Hue and Saturation are represented in the circular color map, while Intensity is shown as a gradient bar.
The white outline in the color map includes the range of colors that would define a Blob, while the bars on the gradient
bar includes the range of intensities.
7.4.3 Color Match Tool
The Color Match tool behaves somewhat like the Average Grayscale tool; you simply draw an ROI over the color
you wish to check for in future inspections.
The tool takes two inputs--Color Match Percent Threshold and Itensity Match Range-and will automatically generate
a Color Map of Hue, Saturation, and Intensity.
Hue, Saturation, and Intensity is a representation of color space that is closer to human perception of color dynamics.
Hue and Saturation are represented in the circular color map, while Intensity is shown as a gradient bar.
