@spec create(Evision.FileNode.t()) :: t() | {:error, String.t()}

@spec create(binary()) :: t() | {:error, String.t()}

Variant 1:

create

Positional Arguments

\brief Load a modality from file.

Python prototype (for reference only):

create(fn_) -> retval

Variant 2:

create

Positional Arguments

• modality_type: String

Return

• retval: QuantizedPyramid

\brief Form a quantized image pyramid from a source image. \param[in] src The source image. Type depends on the modality. \param[in] mask Optional mask. If not empty, unmasked pixels are set to zero

             in quantized image and cannot be extracted as features.
