Detailed Description

Filter an image with a 2D binary kernel composed with the dilate morphological operation.

Refer to Dilate for more details and usage examples regarding Dilate.

Function Documentation

Runs a 2D dilate over an image.

Parameters

[in]	stream	The stream handle where the operation will be queued in. 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 dilated with the kernel. Must not be NULL. Image must have enabled the backends that will execute the algorithm. Supported formats: VPI_IMAGE_FORMAT_U8 VPI_IMAGE_FORMAT_S8 VPI_IMAGE_FORMAT_U16 VPI_IMAGE_FORMAT_S16
[out]	output	Output image where the result is written to. Must not be NULL. Its image format and dimensions must be the same as input. Image must have enabled the backends that will execute the algorithm.
[in]	kernelWidth,kernelHeight	Kernel dimensions. Must be between 1x1 and 11x11, and can be non-square.
[in]	kernelData	Dilate kernel binary mask, i.e. structuring element or neighborhood definition, in row-major layout. The kernel elements are copied to an internal buffer. The buffers passed can be deallocated after the call. Use NULL for full neighborhood, all elements considered to be 1. If not NULL, it must point to a buffer with `kernelWidth` * `kernelHeight` elements.
[in]	border	How to handle pixels outside image boundaries. The accepted border extensions are: VPI_BORDER_ZERO VPI_BORDER_CLAMP VPI_BORDER_REFLECT VPI_BORDER_MIRROR VPI_BORDER_LIMITED (ignore pixels outside image boundaries)

Return values

VPI_ERROR_INVALID_ARGUMENT	`stream` is NULL.
VPI_ERROR_INVALID_ARGUMENT	`input` or `output` are NULL.
VPI_ERROR_INVALID_ARGUMENT	`kernelWidth` or `kernelHeight` outside valid range.
VPI_ERROR_INVALID_ARGUMENT	`input` and `output` images must have same dimensions and format.
VPI_ERROR_INVALID_ARGUMENT	`border` not supported.
VPI_ERROR_INVALID_IMAGE_FORMAT	`input` format not supported.
VPI_ERROR_NOT_IMPLEMENTED	Dilate 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.
