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.
