Closes the image by

performing dilations

followed by erosions.

void iplClose(IplImage*

, IplImage*

int

nIterations

);

srcImage

Thesourceimage.

dstImage

The resultant image.

nIterations

The number of times to dilate and erode the image.

Discussion

The function iplClose() performs

nIterations

of dilation followed by

nIterations

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

respectively.

The process of closing has the effect of filling small and thin holes in

objects, connecting nearby objects, and generally smoothing the boundaries

of objects without significantly changing their area.
