Function Documentation

vpiCreateExtractColorNameFeatures()

VPIStatus vpiCreateExtractColorNameFeatures	(	VPIStream	stream,
		VPIImageType	outType,
		VPIPayload *	payload
	)

#include <vpi/experimental/ColorNames.h>

Creates the payload for the Color Names algorithm.

Parameters

stream	[in] Stream where the algorithm will run.
outType	[in] Type of the output images. It must be one of: VPI_IMAGE_TYPE_S8 VPI_IMAGE_TYPE_U8 VPI_IMAGE_TYPE_S16 VPI_IMAGE_TYPE_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

payload

[out] 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	(	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

payload	[in] Payload to be submitted
input	[in] Input image. The following image types are accepted: VPI_IMAGE_TYPE_RGB8 VPI_IMAGE_TYPE_RGBA8 VPI_IMAGE_TYPE_NV12
output	[out] 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.
numOutputs	[in] 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.
