◆ rppt_color_to_greyscale_gpu()

RppStatus rppt_color_to_greyscale_gpu	(	RppPtr_t	srcPtr,
		RpptDescPtr	srcDescPtr,

	)

Color to greyscale operation on HIP 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.
