Detailed Description

Function Documentation

vxTensorSubtractNode()

VX_API_ENTRY vx_node VX_API_CALL vxTensorSubtractNode	(	vx_graph	graph,
		vx_tensor	input1,
		vx_tensor	input2,
		vx_enum	policy,
		vx_tensor	output )

#include <vx_nodes.h>

[Graph] Performs arithmetic subtraction 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 and VX_TYPE_INT8, with fixed_point_position 0.
[in]	input2	Input tensor data. The dimensions and sizes of input2 match those of input1, unless the vx_tensor of one or more dimensions in input2 is 1. In this case, those dimensions are treated as if this tensor was expanded to match the size of the corresponding dimension of input1, and data was duplicated on all terms in that dimension. After this expansion, the dimensions will be equal. The data type must match the data type of Input1.
[in]	policy	A vx_convert_policy_e enumeration.
[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.

vxuTensorSubtract()

VX_API_ENTRY vx_status VX_API_CALL vxuTensorSubtract	(	vx_context	context,
		vx_tensor	input1,
		vx_tensor	input2,
		vx_enum	policy,
		vx_tensor	output )

#include <vxu.h>

[Immediate] Performs arithmetic subtraction 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 and VX_TYPE_INT8, with fixed_point_position 0.
[in]	input2	Input tensor data. The dimensions and sizes of input2 match those of input1, unless the vx_tensor of one or more dimensions in input2 is 1. In this case, those dimensions are treated as if this tensor was expanded to match the size of the corresponding dimension of input1, and data was duplicated on all terms in that dimension. After this expansion, the dimensions will be equal. The data type must match the data type of Input1.
[in]	policy	A vx_convert_policy_e enumeration.
[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.
