The OpenVX Specification  a73e458

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.

vx_image  output 
)

[Graph] Creates a Remap Node.

Parameters
[in]graphThe reference to the graph that will contain the node [R00389].
[in]inputThe input VX_DF_IMAGE_U8 image [R00390].
[in]tableThe remap table object [R00391].
[in]policyAn interpolation type from Interpolation Constants. VX_INTERPOLATION_AREA is not supported [R00392].
[out]outputThe 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].
Return values
vx_nodeA node reference. Any possible errors preventing a successful creation should be checked using vxGetStatus
