vpiSubmitErode()

VPIStatus vpiSubmitErode	(	VPIStream	stream,
		uint32_t	backend,
		VPIImage	input,

#include <vpi/algo/MorphologicalFilter.h>

Runs a 2D erode over an image.

Parameters

[in]	stream	The stream handle where the operation will be queued in.
[in]	backend	Backend that will execute the algorithm.
[in]	input	Input image to be eroded with the kernel.
[out]	output	Output image where the result is written to. Its image format and dimensions must be the same as input.
[in]	kernelWidth,kernelHeight	Kernel dimensions.
[in]	kernelData	Erode kernel binary mask, i.e. structuring element or neighborhood definition, in row-major layout. Use nullptr for full neighborhood.
[in]	border	Border extension (use VPI_BORDER_INVALID to avoid outside pixels).

Returns

an error code on failure else VPI_SUCCESS.
