followed by dilations.

void iplOpen(IplImage*

srcImage

, IplImage*

dstImage

int

nIterations

);

srcImage

Thesourceimage.

dstImage

The resultant image.

nIterations

The number of times to erode and dilate the

image.

Discussion

The function iplOpen() performs

nIterations

of erosion followed by

nIterations

of dilation performed by iplErode() and iplDilate(),

respectively.

The process of opening has the effect of eliminating small and thin objects,

breaking objects at thin points, and generally smoothing the boundaries of

larger objects without significantly changing their area.
