Detailed Description

Function Documentation

vxMagnitudeNode()

VX_API_ENTRY vx_node VX_API_CALL vxMagnitudeNode	(	vx_graph	graph,
		vx_image	grad_x,
		vx_image	grad_y,
		vx_image	mag )

#include <vx_nodes.h>

[Graph] Create a Magnitude node.

Parameters

[in]	graph	The reference to the graph.
[in]	grad_x	The input x image. This must be in VX_DF_IMAGE_S16 format.
[in]	grad_y	The input y image. This must be in VX_DF_IMAGE_S16 format.
[out]	mag	The magnitude image. This is in VX_DF_IMAGE_S16 format. Must have the same dimensions as the input image.

Returns

vx_node.

Return values

vx_node

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

vxuMagnitude()

VX_API_ENTRY vx_status VX_API_CALL vxuMagnitude	(	vx_context	context,
		vx_image	grad_x,
		vx_image	grad_y,
		vx_image	mag )

#include <vxu.h>

[Immediate] Invokes an immediate Magnitude.

Parameters

[in]	context	The reference to the overall context.
[in]	grad_x	The input x image. This must be in VX_DF_IMAGE_S16 format.
[in]	grad_y	The input y image. This must be in VX_DF_IMAGE_S16 format.
[out]	mag	The magnitude image. This will be in VX_DF_IMAGE_S16 format.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
