Detailed Description

Function Documentation

vxuWeightedAverage()

VX_API_ENTRY vx_status VX_API_CALL vxuWeightedAverage	(	vx_context	context,
		vx_image	img1,
		vx_scalar	alpha,
		vx_image	img2,
		vx_image	output )

#include <vxu.h>

[Immediate] Computes a weighted average image.

Parameters

[in]	context	The reference to the overall context.
[in]	img1	The first VX_DF_IMAGE_U8 image.
[in]	alpha	A VX_TYPE_FLOAT32 type, the input value with the range \( 0.0 \le \alpha \le 1.0 \).
[in]	img2	The second VX_DF_IMAGE_U8 image.
[out]	output	The output VX_DF_IMAGE_U8 image.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.

vxWeightedAverageNode()

VX_API_ENTRY vx_node VX_API_CALL vxWeightedAverageNode	(	vx_graph	graph,
		vx_image	img1,
		vx_scalar	alpha,
		vx_image	img2,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a image weighted average node.

Parameters

[in]	graph	The reference to the graph.
[in]	img1	The first input VX_DF_IMAGE_U8 image.
[in]	alpha	The input VX_TYPE_FLOAT32 scalar value with a value in the range of \( 0.0 \le \alpha \le 1.0 \).
[in]	img2	The second VX_DF_IMAGE_U8 image, which must have the same dimensions as the img1.
[out]	output	The output VX_DF_IMAGE_U8 image, which must have the same dimensions as the img1.

Returns

vx_node.

Return values

vx_node

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