Kernel: Table Lookup

Functions
VX_API_ENTRY vx_node VX_API_CALL	vxTableLookupNode (vx_graph graph, vx_image input, vx_lut lut, vx_image output)
	[Graph] Creates a Table Lookup node. If a value from the input image is not present in the lookup table, the result is undefined.
VX_API_ENTRY vx_status VX_API_CALL	vxuTableLookup (vx_context context, vx_image input, vx_lut lut, vx_image output)
	[Immediate] Processes the image through the LUT.

vxTableLookupNode()

VX_API_ENTRY vx_node VX_API_CALL vxTableLookupNode	(	vx_graph	graph,
		vx_image	input,
		vx_lut	lut,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a Table Lookup node. If a value from the input image is not present in the lookup table, the result is undefined.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16.
[in]	lut	The LUT which is of type VX_TYPE_UINT8 if input image is VX_DF_IMAGE_U8 or VX_TYPE_INT16 if input image is VX_DF_IMAGE_S16.
[out]	output	The output image of the same size 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.

vxuTableLookup()

VX_API_ENTRY vx_status VX_API_CALL vxuTableLookup	(	vx_context	context,
		vx_image	input,
		vx_lut	lut,
		vx_image	output )

#include <vxu.h>

[Immediate] Processes the image through the LUT.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16.
[in]	lut	The LUT which is of type VX_TYPE_UINT8 if input image is VX_DF_IMAGE_U8 or VX_TYPE_INT16 if input image is VX_DF_IMAGE_S16.
[out]	output	The output image of the same size as the input image.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
