vxChannelExtractNode()

VX_API_ENTRY vx_node VX_API_CALL vxChannelExtractNode	(	vx_graph	graph,
		vx_image	input,
		vx_enum	channel,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a channel extract node.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input image. Must be one of the defined vx_df_image_e multi-channel formats.
[in]	channel	The vx_channel_e channel to extract.
[out]	output	The output image. Must be VX_DF_IMAGE_U8, and must have the same dimensions as the input image.
