Function Documentation

vpiCreateExtractColorNameFeatures()

VPIStatus vpiCreateExtractColorNameFeatures	(	VPIBackend	backend,
		VPIImageFormat	outType,
		VPIPayload *	payload
	)

#include <vpi/experimental/ColorNames.h>

Creates the payload for the Color Names algorithm.

Parameters

[in]	backend	VPI backend where the algorithm will be executed.
[in]	outType	Type of the output images. It must be one of: VPI_IMAGE_FORMAT_S8 VPI_IMAGE_FORMAT_U8 VPI_IMAGE_FORMAT_S16 VPI_IMAGE_FORMAT_U16

16-bit types will return more precise values, in exchange of some minor performance hit. 8-bit types will be less precise, but typically leads to faster execution time.

Parameters

[out]

payload

Pointer to a handle that will receive the created payload.

Returns

VPI_SUCCESS if payload creation succeeded, or any other VPIStatus value in case of error.

vpiSubmitExtractColorNameFeatures()

VPIStatus vpiSubmitExtractColorNameFeatures	(	VPIStream	stream,
		VPIPayload	payload,
		VPIImage	input,
		VPIImage *	output,
		int	numOutputs
	)

#include <vpi/experimental/ColorNames.h>

Submits the Color Names algorithm to the stream associated with the payload.

Parameters

[in]	stream	The stream where the operation will be queued in.
[in]	payload	Payload to be submitted along the other parameters.
[in]	input	Input image. The following image types are accepted: VPI_IMAGE_FORMAT_RGB8 VPI_IMAGE_FORMAT_RGBA8 VPI_IMAGE_FORMAT_NV12
[out]	output	Pointer to an array of VPIImage where the features will be written to. The images must have the same type as set during payload creation.
[in]	numOutputs	Number of images in output array. It must be equal to 10.

Returns

VPI_SUCCESS if payload creation succeeded, or any other VPIStatus value in case of error.
