Apply Shape Adaptive Blur.

The filter accepts the following options:

'luma_radius, lr'

Set luma blur filter strength, must be a value in range 0.1-4.0, default value is 1.0. A greater value will result in a more blurred image, and in slower processing.

'luma_pre_filter_radius, lpfr'

Set luma pre-filter radius, must be a value in the 0.1-2.0 range, default value is 1.0.

'luma_strength, ls'

Set luma maximum difference between pixels to still be considered, must be a value in the 0.1-100.0 range, default value is 1.0.

'chroma_radius, cr'

Set chroma blur filter strength, must be a value in range -0.9-4.0. A greater value will result in a more blurred image, and in slower processing.

'chroma_pre_filter_radius, cpfr'

Set chroma pre-filter radius, must be a value in the -0.9-2.0 range.

'chroma_strength, cs'

Set chroma maximum difference between pixels to still be considered, must be a value in the -0.9-100.0 range.

Each chroma option value, if not explicitly specified, is set to the corresponding luma option value.
