Computes the size of the external buffer for the Laplace filter with border.

Syntax

IppStatus ippiFilterLaplacianGetBufferSize_<mod>(IppiSize roiSize, IppiMaskSize mask, int* pBufferSize);

Supported values for mod:

8u16s_C1R 32f_C1R

Include Files

ippcv.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h, ippi.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib

Parameters

roiSize

Maximum size of the source and destination image ROI.

mask

Predefined mask of IppiMaskSize type.

pBufferSize

Pointer to the buffer size.

Description

This function computes the size of the external buffer that is required for the filter function ippiFilterLaplacianBorder. The kernel of the filter is the matrix of either 3x3 or 5x5 size that is specified by the parameter mask (see Table “Types of the Fixed Filter Functions”). This buffer pBufferSize[0] can be used to filter an image whose width and height are equal to or less than corresponding fields of roiSize.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition if the pBufferSize pointer is NULL.

ippStsSizeErr

Indicates an error condition if roiSize has a field with a zero or negative value.

ippStsMaskSizeErr

Indicates an error condition if mask has a wrong value.
