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 [R00107]. A remap is typically defined as:

\[ output(x,y)=input(mapx(x,y),mapy(x,y)); \]

for every (x,y) in the destination image

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

	)

[Graph] Creates a Remap Node.

Parameters

[in]	graph	The reference to the graph that will contain the node [R00389].
[in]	input	The input VX_DF_IMAGE_U8 image [R00390].
[in]	table	The remap table object [R00391].
[in]	policy	An interpolation type from Interpolation Constants. VX_INTERPOLATION_AREA is not supported [R00392].
[out]	output	The output VX_DF_IMAGE_U8 image [R00393].

Note

The border modes VX_NODE_BORDER value VX_BORDER_UNDEFINED and VX_BORDER_CONSTANT are supported.

Returns

A vx_node [R00394].
