Remap

Detailed Description

Maps output pixels in an image from input pixels in an image.

Remap takes a remap table object vx_remap to map a set of output pixels back to source input pixels. A remap is typically defined as:

\[ output(x1,y1) = input(map_x(x0,y0),map_y(x0,y0)) \]

However, the mapping functions are contained in the vx_remap object.

vx_node vxRemapNode	(	vx_graph	graph,
		vx_image	input,
		vx_remap	table,
		vx_enum	policy,
		vx_image	output
	)

[Graph] Creates a Remap Node.

Parameters

[in]	graph	The reference to the graph that will contain the node.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in]	table	The remap table object.
[in]	policy	An interpolation type from vx_interpolation_type_e. VX_INTERPOLATION_TYPE_AREA is not supported.
[out]	output	The output VX_DF_IMAGE_U8 image.

Note

Only VX_NODE_ATTRIBUTE_BORDER_MODE value VX_BORDER_MODE_UNDEFINED or VX_BORDER_MODE_CONSTANT is supported.

Returns

A vx_node.

Return values

0	Node could not be created.
*	Node handle.

vx_status vxuRemap	(	vx_context	context,
		vx_image	input,
		vx_remap	table,
		vx_enum	policy,
		vx_image	output
	)

[Immediate] Remaps an output image from an input image.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in]	table	The remap table object.
[in]	policy	The interpolation policy from vx_interpolation_type_e. VX_INTERPOLATION_TYPE_AREA is not supported.
[out]	output	The output VX_DF_IMAGE_U8 image.

Returns

A vx_status_e enumeration.
