ocmath_dilate_matrix_with_strel

Description

Dilates grayscale and binary image.

Syntax

int ocmath_dilate_matrix_with_strel( int nRows, int nCols, double * pMat, StrelResult * pStrel )


Parameters

nRows
[input] row number of the matrix
nCols
[input] column number of the matrix
pMat
[modify] on input, pointer to the matrix that will be dilated; on output, pointer to the matrix after dilated.
pStrel
[input] pointer to the object of structure StrelResult. StrelResult defines a morphological structuring element.
It has 4 elements:
pNHoodMat: pointer to neighborhood matrix. The neighborhood matrix specifies the neighborhood.
pHeightMat: pointer to height matrix. The height matrix must be real and finite valued and same size as the neighborhood matrix. When it is NULL or all cells of it equals 0, se is flat structuring element, or else nonflat.
nRows: the row number of matrix;
nCols: the column number of matrix;

Return

Returns 0 on success and a non-zero error code on failure.

Examples

EX1

void ocmath_dilate_matrix_with_strel_ex1()
{
matrix matData = {{0,0,0,0,0},
{0,1,2,3,0},
{0,2,3,4,0},
{0,3,4,5,0},
{0,0,0,0,0}};

matrix matHood =  {{0,1,0},{1,2,1},{0,1,0}};
matrix matHeight;
matHeight = matHood;
StrelResult se;
se.nRows = 3;
se.nCols = 3;
se.pNHoodMat = matHood;
se.pHeightMat = matHeight;
int nRet = ocmath_dilate_matrix_with_strel(5, 5, matData, &se);
if(nRet != OE_NOERROR)
printf("  Error: ocmath_dilate_matrix_with_strel failed. Error Code=%d\n", nRet);
