Runs a 2D bilateral filter over an image.

Parameters

[in]	stream	A stream handle where the operation will be queued into. Must not be NULL. Stream must have enabled the backends that will execute the algorithm.
[in]	backend	Backend that will execute the algorithm. Valid values: VPI_BACKEND_CPU VPI_BACKEND_CUDA
[in]	input	Input image to be filtered. Must not be NULL. Image must have enabled the backends that will execute the algorithm. The accepted image formats are: Formats CPU CUDA VPI_IMAGE_FORMAT_U8 * * VPI_IMAGE_FORMAT_S8 * * VPI_IMAGE_FORMAT_U16 * * VPI_IMAGE_FORMAT_S16 * * VPI_IMAGE_FORMAT_Y8 * * VPI_IMAGE_FORMAT_Y8_ER * * VPI_IMAGE_FORMAT_Y16 * * VPI_IMAGE_FORMAT_Y16_ER * * VPI_IMAGE_FORMAT_F32 * * VPI_IMAGE_FORMAT_NV12 * VPI_IMAGE_FORMAT_NV12_ER *
[out]	output	Output image where the result will be written to. Must not be NULL. It must have the same format and dimensions as input. Image must have enabled the backends that will execute the algorithm.
[in]	kernelSize	Kernel support dimensions, in pixels. Must be >= 1 and <= 11. Must be odd.
[in]	sigmaRange	Standard deviation in color space. Must be > 0.
[in]	sigmaSpace	Standard deviation in the coordinate space. Must be > 0.
[in]	border	How to handle pixels outside image boundaries. The accepted border extensions are: VPI_BORDER_ZERO VPI_BORDER_CLAMP

VPI_ERROR_INVALID_ARGUMENT	kernelSize outside valid range.
VPI_ERROR_INVALID_ARGUMENT	sigmaRange or sigmaSpace outside valid range.
VPI_ERROR_INVALID_ARGUMENT	backend is invalid or unknown.
VPI_ERROR_INVALID_ARGUMENT	border not supported.
VPI_ERROR_INVALID_IMAGE_FORMAT	input or output format is not supported.
VPI_ERROR_NOT_IMPLEMENTED	Bilateral Filter algorithm is not supported by given backend.
VPI_ERROR_INVALID_OPERATION	The needed backends aren't enabled in stream, input or output.
VPI_SUCCESS	Operation executed successfully.
