Detailed Description

Dilation(morphological operator) for images.

The dilation function takes two pieces of data as inputs. The first is the input image to be morphed, and the second is the mask indicating the neighborhood around each pixel to match.

In dilation, for each pixel, the mask is centered at the pixel. If the center pixel of the mask matches the corresponding pixel on the image, then the mask is accepted. If the center pixels do not matches, then the mask is ignored and no changes are made.

Function Documentation

AFAPI af_err af_dilate	(	af_array *	out,
		const af_array	in,
		const af_array	mask
	)

C Interface for image dilation (max filter)

Parameters

[out]	out	array is the dilated image
[in]	in	array is the input image
[in]	mask	is the neighborhood window

Returns

AF_SUCCESS if the dilated successfully, otherwise an appropriate error code is returned.

Note

if mask is all ones, this function behaves like max filter

AFAPI array af::dilate	(	const array &	in,
		const array &	mask
	)

C++ Interface for image dilation (max filter)

Parameters

[in]	in	array is the input image
[in]	mask	is the neighborhood window

Returns

the dilated image

Note

if mask is all ones, this function behaves like max filter
