vxuWarpPerspective()

VX_API_ENTRY vx_status VX_API_CALL vxuWarpPerspective	(	vx_context	context,
		vx_image	input,
		vx_matrix	matrix,
		vx_enum	type,
		vx_image	output )

#include <vxu.h>

[Immediate] Performs an Perspective warp on an image.

Parameters

[in]	context	The reference to the overall context.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in]	matrix	The perspective matrix. Must be 3x3 of type VX_TYPE_FLOAT32.
[in]	type	The interpolation type from vx_interpolation_type_e. VX_INTERPOLATION_AREA is not supported.
[out]	output	The output VX_DF_IMAGE_U8 image.

Returns

A vx_status_e enumeration.

Return values

VX_SUCCESS	Success
*	An error occurred. See vx_status_e.

vxWarpPerspectiveNode()

VX_API_ENTRY vx_node VX_API_CALL vxWarpPerspectiveNode	(	vx_graph	graph,
		vx_image	input,
		vx_matrix	matrix,
		vx_enum	type,
		vx_image	output )

#include <vx_nodes.h>

[Graph] Creates a Perspective Warp Node.

Parameters

[in]	graph	The reference to the graph.
[in]	input	The input VX_DF_IMAGE_U8 image.
[in]	matrix	The perspective matrix. Must be 3x3 of type VX_TYPE_FLOAT32.
[in]	type	The interpolation type from vx_interpolation_type_e. VX_INTERPOLATION_AREA is not supported.
[out]	output	The output VX_DF_IMAGE_U8 image.

Note

The border modes VX_NODE_BORDER value VX_BORDER_UNDEFINED and VX_BORDER_CONSTANT are supported.

Returns

vx_node.

Return values

vx_node

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