Detailed Description

Function Documentation

vxNonMaxSuppressionNode()

VX_API_ENTRY vx_node VX_API_CALL vxNonMaxSuppressionNode	(	vx_graph	graph,
		vx_image	input,
		vx_image	mask,
		vx_int32	win_size,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a Non-Maxima Suppression node.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[in]	mask	[optional] Constrict suppression to a ROI. The mask image is of type VX_DF_IMAGE_U8 or VX_DF_IMAGE_U1 and must have the same dimensions as the input image.
[in]	win_size	The size of window over which to perform the localized non-maxima suppression. Must be odd, and less than or equal to the smallest dimension of the input image.
[out]	output	The output image, of the same type and size as the input, that has been non-maxima suppressed.

Returns

vx_node.

Return values

vx_node

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

vxuNonMaxSuppression()

VX_API_ENTRY vx_status VX_API_CALL vxuNonMaxSuppression	(	vx_context	context,
		vx_image	input,
		vx_image	mask,
		vx_int32	win_size,
		vx_image	output )

#include <vxu.h>

[Immediate] Performs Non-Maxima Suppression on an image, producing an image of the same type.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 format.
[in]	mask	[optional] Constrict suppression to a ROI. The mask image is of type VX_DF_IMAGE_U8 or VX_DF_IMAGE_U1 and must be the same dimensions as the input image.
[in]	win_size	The size of window over which to perform the localized non-maxima suppression. Must be odd, and less than or equal to the smallest dimension of the input image.
[out]	output	The output image, of the same type as the input, that has been non-maxima suppressed.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.
