vxLBPNode()

VX_API_ENTRY vx_node VX_API_CALL vxLBPNode	(	vx_graph	graph,
		vx_image	in,
		vx_enum	format,
		vx_int8	kernel_size,
		vx_image	out )

#include <vx_nodes.h>

[Graph] Creates a node that extracts LBP image from an input image

Parameters

[in]	graph	The reference to the graph.
[in]	in	An input image in vx_image. Or \( SrcImg\) in the equations. the image is of type VX_DF_IMAGE_U8
[in]	format	A variation of LBP like original LBP and mLBP. see vx_lbp_format_e
[in]	kernel_size	Kernel size. Only size of 3 and 5 are supported
[out]	out	An output image in vx_image.Or \( DstImg\) in the equations. the image is of type VX_DF_IMAGE_U8 with 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

vxuLBP()

VX_API_ENTRY vx_status VX_API_CALL vxuLBP	(	vx_context	context,
		vx_image	in,
		vx_enum	format,
		vx_int8	kernel_size,
		vx_image	out )

#include <vxu.h>

[Immediate] The function extracts LBP image from an input image

Parameters

[in]	context	The reference to the overall context.
[in]	in	An input image in vx_image. Or \( SrcImg\) in the equations. the image is of type VX_DF_IMAGE_U8
[in]	format	A variation of LBP like original LBP and mLBP. see vx_lbp_format_e
[in]	kernel_size	Kernel size. Only size of 3 and 5 are supported
[out]	out	An output image in vx_image.Or \( DstImg\) in the equations. the image is of type VX_DF_IMAGE_U8

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
