Tensor TableLookUp

## Detailed Description

Performs LUT on element values in the input tensor data.

This kernel uses each element in a tensor to index into a LUT and put the indexed LUT value into the output tensor. The tensor types supported are VX_TYPE_UINT8 and VX_TYPE_INT16. Signed inputs are cast to unsigned before used as input indexes to the LUT.

## Function Documentation

 vx_node VX_API_CALL vxTensorTableLookupNode ( vx_graph graph, vx_tensor input1, vx_lut lut, vx_tensor output )

[Graph] Performs LUT on element values in the input tensor data.

Parameters
 [in] graph The handle to the graph. [in] input1 Input tensor data. Implementations must support input tensor data type VX_TYPE_INT16 with fixed_point_position 8, and tensor data types VX_TYPE_UINT8, with fixed_point_position 0. [in] lut The look-up table to use, of type vx_lut. The elements of input1 are treated as unsigned integers to determine an index into the look-up table. The data type of the items in the look-up table must match that of the output tensor. [out] output The output tensor data with the same dimensions as the input tensor data.
Returns
vx_node.
A node reference vx_node. Any possible errors preventing a successful creation should be checked using vxGetStatus.
 vx_status VX_API_CALL vxuTensorTableLookup ( vx_context context, vx_tensor input1, vx_lut lut, vx_tensor output )

[Immediate] Performs LUT on element values in the input tensor data.

Parameters
 [in] context The reference to the overall context. [in] input1 Input tensor data. Implementations must support input tensor data type VX_TYPE_INT16 with fixed_point_position 8, and tensor data types VX_TYPE_UINT8, with fixed_point_position 0. [in] lut The look-up table to use, of type vx_lut. The elements of input1 are treated as unsigned integers to determine an index into the look-up table. The data type of the items in the look-up table must match that of the output tensor. [out] output The output tensor data with the same dimensions as the input tensor data.
Returns
A vx_status_e enumeration.
Return values
 VX_SUCCESS Success * An error occurred. See vx_status_e.
