will be weighted in the output image. A higher value produces a
smoother grayscale image. Minimum is 0, maximum is 255.
5 If needed, add a new color range to the list in the Colors section.
Each pixel of the output image is computed as the corresponding maximum
output pixel of all individual color range filters.
6 If needed, adjust the smoothing factor to reduce noise in the resulting
grayscale image.
7 Click OK to close the dialog.

8 Proceed to define the object recognition model.
Tip
Filter ranges should be narrow to provide an output image with high contrast.
From an image quality perspective, it is often better to select small
homogeneously colored samples and add several ranges to the list of colors.
Tip
Try to filter with both RGB and HSI. Sometimes one may work significantly better
than the other.
Example 1
This example describes how to locate a part with PatMax and inspect the color
with Blob.
1 Create an inspection model, see Configuring inspection models on page 264.
2 Create a PatMax alignment model. Use color filtering if contrast needs to be
increased, or use the unfiltered monochrome image if there is sufficient
contrast.
