◆ rppt_channel_permute()

RppStatus rppt_channel_permute	(	RppPtr_t	srcPtr,
		RpptDescPtr	srcDescPtr,
		RppPtr_t	dstPtr,
		RpptDescPtr	dstDescPtr,
		Rpp32u *	permutationTensor,
		rppHandle_t	rppHandle,
		RppBackend	executionBackend
	)

Channel permute operation on HIP/HOST backend for a NCHW/NHWC layout tensor.

This function performs one of six possible channel permutations (R-G-B, R-B-G, G-R-B, G-B-R, B-R-G, B-G-R) for an image in a batch of RGB(3 channel) images with an NHWC/NCHW tensor layout.

• srcPtr depth ranges - Rpp8u (0 to 255), Rpp16f (0 to 1), Rpp32f (0 to 1), Rpp8s (-128 to 127).
• dstPtr depth ranges - Will be same depth as srcPtr.

  Sample Output

  Parameters

  [in]	srcPtr	source tensor in HIP memory (for HIP backend) or HOST memory (for HOST backend)
  [in]	srcDescPtr	source tensor descriptor (Restrictions - numDims = 4, offsetInBytes >= 0, dataType = U8/F16/F32/I8, layout = NCHW/NHWC, c = 3)
  [out]	dstPtr	destination tensor in HIP memory (for HIP backend) or HOST memory (for HOST backend)
  [in]	dstDescPtr	destination tensor descriptor (Restrictions - numDims = 4, offsetInBytes >= 0, dataType = U8/F16/F32/I8, layout = NCHW/NHWC, c = same as that of srcDescPtr)
  [in]	permutationTensor	A tensor in HIP memory (for HIP backend) or HOST memory (for HOST backend) specifying the channel permutation for each image. Size: 3 × srcDescPtr->n. Each value must satisfy: 0 ≤ permutationTensor[i] ≤ 2.
  [in]	rppHandle	RPP HIP/HOST handle created with rppCreate()
  [in]	executionBackend	backend for execution (RppBackend::RPP_HOST_BACKEND or RppBackend::RPP_HIP_BACKEND)

  Returns

  A RppStatus enumeration.

  Return values

  RPP_SUCCESS	Successful completion.
  RPP_ERROR*	Unsuccessful completion.

◆ rppt_color_to_greyscale()

RppStatus rppt_color_to_greyscale	(	RppPtr_t	srcPtr,
		RpptDescPtr	srcDescPtr,
		RppPtr_t	dstPtr,
		RpptDescPtr	dstDescPtr,
		RpptSubpixelLayout	srcSubpixelLayout,
		rppHandle_t	rppHandle,
		RppBackend	executionBackend
	)

Color to greyscale operation on HIP/HOST backend for a NCHW/NHWC layout tensor.

The color to greyscale operation runs for a batch of RGB(3 channel) images with an NHWC/NCHW tensor layout.

• srcPtr depth ranges - Rpp8u (0 to 255), Rpp16f (0 to 1), Rpp32f (0 to 1), Rpp8s (-128 to 127).
• dstPtr depth ranges - Will be same depth as srcPtr.
