Property Details
The “param1” property
“param1” gint
The aperture width (Must be positive and odd).Check cvSmooth OpenCV docs: http://opencv.willowgarage.com/documentation/image_filtering.php#cvSmooth.
Flags: Read / Write
Allowed values: >= 1
Default value: 3
The “param2” property
“param2” gint
The aperture height, if zero, the width is used.(Must be positive and odd or zero, unuset in median and bilateral types). Check cvSmooth OpenCV docs: http://opencv.willowgarage.com/documentation/image_filtering.php#cvSmooth.
Flags: Read / Write
Allowed values: >= 0
Default value: 0
The “param3” property
“param3” gdouble

Flags: Read / Write
Allowed values: >= 0
Default value: 0
The “param4” property
“param4” gdouble
Only used in bilateral type, means the spatial-sigma.Check cvSmooth OpenCV docs: http://opencv.willowgarage.com/documentation/image_filtering.php#cvSmooth.
