## Functions

## Types and Values

### struct GstCvSmooth

    struct GstCvSmooth;

## 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.html#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.html#cvSmooth.

Flags: Read / Write

Allowed values: >= 0

Default value: 0

### The `“param3”` property

      “param3”                   gdouble

If type is gaussian, this means the standard deviation.If type is bilateral, this means the color-sigma. If zero, Default values are used.Check cvSmooth OpenCV docs: http://opencv.willowgarage.com/documentation/image_filtering.html#cvSmooth.

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.html#cvSmooth.

Flags: Read / Write

Allowed values: >= 0

Default value: 0

### The `“type”` property

      “type”                     GstCvSmoothTypeType

Smooth Type.

Flags: Read / Write

Default value: CV Gaussian

### The `“color”` property

      “color”                    gdouble

If type is gaussian, this means the standard deviation.If type is bilateral, this means the color-sigma. If zero, Default values are used.

Flags: Read / Write

Allowed values: >= 0

Default value: 0

### The `“height”` property

      “height”                   gint

The gaussian kernel height (must be positive and odd).

Flags: Read / Write

Allowed values: >= 0

Default value: 3

### The `“spatial”` property

      “spatial”                  gdouble

Only used in bilateral type, means the spatial-sigma.

Flags: Read / Write

Allowed values: >= 0

Default value: 0

### The `“width”` property

      “width”                    gint

The gaussian kernel width (must be positive and odd).If type is median, this means the aperture linear size.Check OpenCV docs: http://docs.opencv.org/2.4/modules/imgproc/doc/filtering.htm.

Flags: Read / Write

Allowed values: >= 1

Default value: 3
