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.

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.
