The OpenVX Specification
2b213f9
|
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 formats supported are VX_DF_IMAGE_U8
and VX_DF_IMAGE_S16
.
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. If a value from the input image is not present in the lookup table, the result is undefined. 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. If a value from the input image is not present in the lookup table, the result is undefined.
[in] | graph | The reference to the graph. |
[in] | input | The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 . |
[in] | lut | The LUT which is of type VX_TYPE_UINT8 or VX_TYPE_INT16 . |
[out] | output | The output image of the same type as the input image. |
vx_node
. vx_node | A node reference. Any possible errors preventing a successful creation should be checked using vxGetStatus . |
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.
[in] | context | The reference to the overall context. |
[in] | input | The input image in VX_DF_IMAGE_U8 or VX_DF_IMAGE_S16 . |
[in] | lut | The LUT which is of type VX_TYPE_UINT8 or VX_TYPE_INT16 . |
[out] | output | The output image of the same type as the input image. |
vx_status_e
enumeration. VX_SUCCESS | Success |
* | An error occurred. See vx_status_e . |
