The OpenVX Specification
r31169
|
Implements the Table Lookup Image Kernel.
This kernel uses each pixel in an image to index into a LUT and put the indexed LUT value into the output image. The format supported is VX_DF_IMAGE_U8
.
Functions | |
vx_node VX_API_CALL | vxTableLookupNode (vx_graph graph, vx_image input, vx_lut lut, vx_image output) |
[Graph] Creates a Table Lookup node. More... | |
vx_status VX_API_CALL | vxuTableLookup (vx_context context, vx_image input, vx_lut lut, vx_image output) |
[Immediate] Processes the image through the LUT. More... | |
vx_node VX_API_CALL vxTableLookupNode | ( | vx_graph | graph, |
vx_image | input, | ||
vx_lut | lut, | ||
vx_image | output | ||
) |
[Graph] Creates a Table Lookup node.
[in] | graph | The reference to the graph. |
[in] | input | The input image in VX_DF_IMAGE_U8 . |
[in] | lut | The LUT which is of type VX_TYPE_UINT8 . |
[out] | output | The output image of type VX_DF_IMAGE_U8 . |
vx_node
. vx_node | A node reference. Any possible errors preventing a successful creation should be checked using vxGetStatus |

[in] | context | The reference to the overall context. |
[in] | input | The input image in VX_DF_IMAGE_U8 |
[in] | lut | The LUT which is of type VX_TYPE_UINT8 |
[out] | output | The output image of type VX_DF_IMAGE_U8 |
