Setting value
Set the number of times the filter is applied.
Set an odd value for the size of the filter mask.
If there are large variations in the brightness of peripheral pixels, increase the
"Mask size" setting.
Set the divisor for pixel values after masking.
The value that results from dividing the result of masking by the "Filter
divisor" and adding the offset is the filtered pixel value.
Set together with the filter coefficients.
Set the offset value for masked pixel values.
The value that results from dividing the result of masking by the "Filter
divisor" and adding the offset is the filtered pixel value.
Set the processing that takes place when filtering results in a negative pixel
value.
• Rounding
Round the pixel value to 1.
• Absolute
Use the absolute value of the pixel value.
To set all filter values at once, select the "Set all" checkbox.
For the coefficients for the pixel values in masking, set the number of
coefficients that is equal to the mask size.
Set together with the filter divisor.
