Function Documentation

VX_API_ENTRY vx_node VX_API_CALL tivxDmpacSdeNode	(	vx_graph	graph,
		vx_user_data_object	configuration,
		vx_image	left,
		vx_image	right,
		vx_image	output,
		vx_distribution	confidence_histogram
	)

[Graph] Creates a DMPAC_SDE Node.

Parameters

[in]	graph	The reference to the graph.
[in]	configuration	The input object of a single params structure of type `tivx_dmpac_sde_params_t`.
[in]	left	The left input image in `VX_DF_IMAGE_U8`, `VX_DF_IMAGE_NV12` (Y plane only), `VX_DF_IMAGE_U16`, or `TIVX_DF_IMAGE_P12` format.
[in]	right	The right input image in `VX_DF_IMAGE_U8`, `VX_DF_IMAGE_NV12` (Y plane only), `VX_DF_IMAGE_U16`, or `TIVX_DF_IMAGE_P12` format.
[out]	output	The output image in `VX_DF_IMAGE_S16` format. Bit packing format: Sign[15], Integer[14:7], Fractional[6:3], Confidence[2:0]. The 3 bit 'Confidence' value is the result of passing the 7-bit confidence score through the user configured tivx_dmpac_sde_params_t::confidence_score_map range table to produce a 3-bit mapping.
[out]	confidence_histogram	(optional) Histogram of the full 7-bit confidence scores. Must be configured to 128 bins.

Return values

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

void tivx_dmpac_sde_params_init ( tivx_dmpac_sde_params_t * prms )

Function to initialize SDE Parameters.

Parameters

prms	[IN] Pointer to SDE parameters
