Detailed Description

Function Documentation

vxConvolveNode()

VX_API_ENTRY vx_node VX_API_CALL vxConvolveNode	(	vx_graph	graph,
		vx_image	input,
		vx_convolution	conv,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a custom convolution node.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input image in VX_DF_IMAGE_U8 format.
[in]	conv	The vx_int16 convolution matrix.
[out]	output	The output image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format, which 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

vxuConvolve()

VX_API_ENTRY vx_status VX_API_CALL vxuConvolve	(	vx_context	context,
		vx_image	input,
		vx_convolution	conv,
		vx_image	output )

#include <vxu.h>

[Immediate] Computes a convolution on the input image with the supplied matrix.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input image in VX_DF_IMAGE_U8 format.
[in]	conv	The vx_int16 convolution matrix.
[out]	output	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.
