@spec setCostMap(t(), Evision.Mat.maybe_mat_in()) :: t() | {:error, String.t()}

Interface to provide a more elaborated cost map, i.e. edge map, for the edge-aware term. This implementation is based on a rather simple gradient-based edge map estimation. To used more complex edge map estimator (e.g. StructuredEdgeDetection that has been used in the original publication) that may lead to improved accuracies, the internal edge map estimation can be bypassed here.

Positional Arguments

• self: Evision.XImgProc.EdgeAwareInterpolator.t()

• costMap: Evision.Mat.t().

  a type CV_32FC1 Mat is required.

@spec setK(t(), integer()) :: t() | {:error, String.t()}

K is a number of nearest-neighbor matches considered, when fitting a locally affine model. Usually it should be around 128. However, lower values would make the interpolation noticeably faster.

Positional Arguments

• self: Evision.XImgProc.EdgeAwareInterpolator.t()
• k: int

Python prototype (for reference only):

setK(_k) -> None

@spec setLambda(t(), number()) :: t() | {:error, String.t()}

Lambda is a parameter defining the weight of the edge-aware term in geodesic distance, should be in the range of 0 to 1000.

Positional Arguments

• self: Evision.XImgProc.EdgeAwareInterpolator.t()
• lambda: float

Python prototype (for reference only):

setLambda(_lambda) -> None

@spec setSigma(t(), number()) :: t() | {:error, String.t()}

Sigma is a parameter defining how fast the weights decrease in the locally-weighted affine fitting. Higher values can help preserve fine details, lower values can help to get rid of noise in the output flow.

Positional Arguments

• self: Evision.XImgProc.EdgeAwareInterpolator.t()
• sigma: float

Python prototype (for reference only):

setSigma(_sigma) -> None

@spec setUsePostProcessing(t(), boolean()) :: t() | {:error, String.t()}

Sets whether the fastGlobalSmootherFilter() post-processing is employed. It is turned on by default.

Positional Arguments

• self: Evision.XImgProc.EdgeAwareInterpolator.t()
• use_post_proc: bool

Python prototype (for reference only):

setUsePostProcessing(_use_post_proc) -> None
