36. Update Deviation Data
Updates deviation data used in deviation differentiation. If the deviation data
is not changed a single degree, then it is set at 1.0 for all pixels. As shown
below, deviation data is changed only for pixels that are converted to 1 in the
threshold value processing performed under the direction of the execution
results of the subtraction processing performed immediately prior. The
formula for calculating deviation data is shown below.
New deviation = (threshold value) / (difference in brightness)
Threshold
value=96
Difference=128
Use the cursor keys to select the results to be used in updating the deviation
data, then press ENTER. A message will appear. Select Yes to update data
or No to leave data unchanged.
37. Put Deviation Data
Restores deviation data to what it was before the last change was made.
38. Initialize Deviation Data
Resets all deviation data to 1.0. Once the data is reset, the values cannot be
restored to what they were prior to the reset.
