Non Linear Filter

Detailed Description

Computes a non-linear filter over a window of the input image. The output image dimensions should be the same as the dimensions of the input image.

The attribute VX_CONTEXT_NONLINEAR_MAX_DIMENSION enables the user to query the largest nonlinear filter supported by the implementation of vxNonLinearFilterNode. The implementation must support all dimensions (height or width, not necessarily the same) up to the value of this attribute. The lowest value that must be supported for this attribute is 9.

vx_node VX_API_CALL vxNonLinearFilterNode	(	vx_graph	graph,
		vx_enum	function,
		vx_image	input,
		vx_matrix	mask,
		vx_image	output
	)

[Graph] Creates a Non-linear Filter Node.

Parameters

[in]	graph	The reference to the graph.
[in]	function	The non-linear filter function. See vx_non_linear_filter_e.
[in]	input	The input image in VX_DF_IMAGE_U8 format.
[in]	mask	The mask to be applied to the Non-linear function. VX_MATRIX_ORIGIN attribute is used to place the mask appropriately when computing the resulting image. See vxCreateMatrixFromPattern.
[out]	output	The output image in VX_DF_IMAGE_U8 format, which must have the same dimensions as the input image.

Returns

vx_node.

Return values

vx_node

A node reference. Any possible errors preventing a successful creation should be checked using vxGetStatus

vx_status VX_API_CALL vxuNonLinearFilter	(	vx_context	context,
		vx_enum	function,
		vx_image	input,
		vx_matrix	mask,
		vx_image	output
	)

[Immediate] Performs Non-linear Filtering.

Parameters

[in]	context	The reference to the overall context.
[in]	function	The non-linear filter function. See vx_non_linear_filter_e.
[in]	input	The input image in VX_DF_IMAGE_U8 format.
[in]	mask	The mask to be applied to the Non-linear function. VX_MATRIX_ORIGIN attribute is used to place the mask appropriately when computing the resulting image. See vxCreateMatrixFromPattern and vxCreateMatrixFromPatternAndOrigin.
[out]	output	The output image in VX_DF_IMAGE_U8 format.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
