Parameters

pSrc

Pointer to the source image ROI.

srcStep

Distance, in bytes, between the starting points of consecutive lines in the source image.

srcBitOffset

Offset, in bits, from the first byte of the source image (for the 1u_C1R flavor).

pDst

Pointer to the destination image ROI.

dstStep

Distance, in bytes, between the starting points of consecutive lines in the destination image.

dstBitOffset

Offset, in bits, from the first byte of the destination image (for the 1u_C1R flavor).

roiSize

Size of the source and destination image ROI.

borderType

Type of border. Possible values are:

ippBorderRepl

Border is replicated from the edge pixels.

ippBorderInMem

Border is obtained from the source image pixels in memory.

borderValue, borderValue[3], borderValue[4]

Constant value to assign to pixels of the constant border. This parameter is applicable only to the ippBorderConst border type.

pSpec

Pointer to the specification structure.

pBuffer

Pointer to the external buffer required for dilation operations.

Description

Before using this function, you need to initialize the morphology specification structure by using MorphAdvInit function.

This function operates with ROI.

This function performs opening of a rectangular ROI area inside a one-, three-, or four-channel 2D image using the mask specified in the pSpec structure.

The result is equivalent to successive dilation of the source image by the structured element (mask) and erosion by the reverted structured element.

NOTE:

The function can only process a ROI that does not exceed the maximum width and height roiSize specified by the initialization functions.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error condition when:

  • roiSize has a field with a zero or negative value

  • one of the ROI width or height is more than the corresponding size of ROI passed to the initialization functions

  • srcBitOffset or dstBitOffset is less than zero

ippStsStepErr

Indicates an error condition if srcStep or dstStep is less than roiSize.width * <pixelSize>.

ippStsNotEvenStepErr

Indicates an error condition if one of the step values for 16-bit integer images is not divisible by 2.

ippStsBorderErr

Indicates an error condition if borderType has an illegal value.
