Detailed Description

Function Documentation

vxAbsDiffNode()

VX_API_ENTRY vx_node VX_API_CALL vxAbsDiffNode	(	vx_graph	graph,
		vx_image	in1,
		vx_image	in2,
		vx_image	out )

#include <vx_nodes.h>

[Graph] Creates an AbsDiff node.

Parameters

[in]	graph	The reference to the graph.
[in]	in1	An input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[in]	in2	An input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[out]	out	The output image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format, which must have the same dimensions as the input image.

Return values

vx_node

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

vxuAbsDiff()

VX_API_ENTRY vx_status VX_API_CALL vxuAbsDiff	(	vx_context	context,
		vx_image	in1,
		vx_image	in2,
		vx_image	out )

#include <vxu.h>

[Immediate] Computes the absolute difference between two images.

Parameters

[in]	context	The reference to the overall context.
[in]	in1	An input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[in]	in2	An input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[out]	out	The output image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
