TableLookup

Detailed Description

Implements the Table Lookup Image Kernel.

This kernel uses each pixel in an image to index into a LUT and put the indexed LUT value into the output image [R00115]. The formats supported are VX_DF_IMAGE_U8 and VX_DF_IMAGE_S16 [R00116].

Functions
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. More...

vxTableLookupNode()

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.

Parameters

[in]	graph	The reference to the graph [R00189].
[in]	input	The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 [R00190].
[in]	lut	The LUT which is of type VX_TYPE_UINT8 or VX_TYPE_INT16 [R00191].
[out]	output	The output image of the same type as the input image [R00192].

Returns

vx_node [R00193].

Return values

vx_node

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