FILTERING OR SMOOTHING IMAGE NOISE OF PHOTOS

If a project seems to have an image take longer than necessary to appear on the screen,

during the Automated Coded Target ETemplate Project Wizard, it is possible to modify the

filtering or smoothing of “image noise.” Following is a screen shot, and the order of steps

regarding Target Marking Preferences that may be modified in order to try to get better results.

STEPS to modify Target Marking Preferences

ETemplate > Options > Preferences > Target Marking tab

1. Edge Filter Sigma: 2.2

Edge Strength High Threshold: 0.3

Edge Strength Low Threshold: 0.2

Try running the project again. If this does not help, try Step 2.

2. Edge Filter Sigma: 2.5

Edge Strength High Threshold: 0.4

Edge Strength Low Threshold: 0.3

Try running the project again.

Please note:

• As these values are set larger in each step, the total quantity of automatically marked

points may be slightly reduced. If desired, reset the settings to the default Target Marking

Preferences by clicking “Reset this Tab to Default Values”

NOTE: “Sub-pixel method threshold size (pixels):” must be manually set to 250

• If not resetting the preferences to the default values, we recommend using step 1

values as primary preference settings and use step 2 values as needed

• “Use Fast Automatic Segmentation” should remain Unchecked in any case
