¶
RadiusLike = int | tuple[int, SpatialConvModeT]
Type alias for specifying a convolution radius.
This can be one of the following
- An
int
: Interpreted as a square convolution with size(2 * radius + 1) x (2 * radius + 1)
. - A
tuple[int, SpatialConvModeT]
: A pair specifying the radius and the convolution mode.

An opening is an erosion followed by an dilation.
Parameters:
-
clip
¶VideoNode
) –Clip to process
-
radius
¶RadiusLike
, default:1
) –A single integer specifies the size of the square matrix. A tuple of an integer and a ConvMode allows specification of the matrix type dimension as well.
-
thr
¶float | None
, default:None
) –Threshold (32-bit scale) to limit how much pixels are changed. Output pixels will not become less than input - thr. The default is no limit.
-
iterations
¶int
, default:1
) –Number of times to execute the function.
-
coords
¶Sequence[int] | None
, default:None
) –Specifies which pixels from the neighbourhood are considered. If an element of this array is 0, the corresponding pixel is not considered when finding the maximum value. This must contain exactly (radius * 2 + 1) ** 2 - 1 numbers eg. 8, 24, 48... When specified, this parameter takes precedence over radius.
-
multiply
¶float | None
, default:None
) –Optional multiplier of the final value.
-
planes
¶PlanesT
, default:None
) –Which plane to process.
