Accumulate

Detailed Description

Accumulates an input image into output image.

Accumulation is computed by:

\[ accum(x,y) = accum(x,y) + input(x,y) \]

The overflow policy used is VX_CONVERT_POLICY_SATURATE.

Function Documentation

vx_node VX_API_CALL vxAccumulateImageNode	(	vx_graph	graph,
		vx_image	input,
		vx_image	accum
	)

[Graph] Creates an accumulate node.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in,out]	accum	The accumulation image in VX_DF_IMAGE_S16.

Returns

vx_node.

Return values

vx_node

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

vx_status VX_API_CALL vxuAccumulateImage	(	vx_context	context,
		vx_image	input,
		vx_image	accum
	)

[Immediate] Computes an accumulation.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in,out]	accum	The accumulation image in VX_DF_IMAGE_S16

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
