Parameters:

    (VideoNode) –

    Clip to process.

  • midthr

    (float | list[float] | None, default: None ) –

    Defaults to the middle point of range allowed by the format. Can be specified for each plane individually.

  • lowval

    (float | list[float] | None, default: None ) –

    Value given to pixels that are below threshold. Can be specified for each plane individually. Defaults to the lower bound of the format.

  • highval

    (float | list[float] | None, default: None ) –

    Value given to pixels that are greater than or equal to threshold. Defaults to the maximum value allowed by the format. Can be specified for each plane individually. Defaults to the upper bound of the format.

  • planes

    (PlanesT, default: None ) –

    Specifies which planes will be processed. Any unprocessed planes will be simply copied.

A bottom hat or a black hat is the difference of the closing and the original clip.

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.

Replaces each pixel with the smallest value in its 3x3 neighbourhood. This operation is also known as erosion with a radius of 1.

Parameters:

  • clip

    (VideoNode) –

    Clip to process.

  • 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 3x3 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 8 numbers.

  • multiply

    (float | None, default: None ) –

    Optional multiplier of the final value.

  • planes

    (PlanesT, default: None ) –

    Which plane to process.

An opening is an erosion followed by an dilation.

Parameters:

    (VideoNode) –

    Clip to process

    (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.

    (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
